The main advantage of a refrigeration incubator is that factory refrigerators have a very important thing: thermal insulation.

In order to begin the process of manufacturing such a device, you first need to determine the number of eggs that you will load into the incubator; for beginning poultry farmers, the optimal number of eggs would be no more than 50.

Requirementswhich need to follow when using an incubator:

    The number of days that must pass before hatching should be at least 10.

During these ten days, eggs should be kept at a distance of about 1-2 centimeters from each other.

The temperature within ten days should be at least 37.3 degrees and not more than 38.6 degrees.

In the period of laying eggs, the humidity should be about 40-60%. Further, when the chicks already begin to appear, the humidity is increased to 80%. As follows at the time of selection of chicks, the humidity is reduced.

Eggs should be in a vertical position with a sharp tip down or in a horizontal position. In the vertical position, eggs in a tray are placed at a 45 degree angle.

If you are trying to hatch ducks and geese, eggs should be at a 90 degree angle.

If the eggs in the tray are arranged horizontally, then they turn over at an angle of 180 degrees, depending on their initial position. Best of all, this turn spends every hour, but at least once every three hours. Before the chicks hatch from the eggs, which is about three days before their hatching, it is better not to roll the eggs.

For a self-made incubator, ventilation is very important. With the help of ventilation is the regulation of temperature and humidity in the incubator. The approximate speed should be about 5 meters per second.

The incubation method for chicks is very close to the natural method.

Scheme of the incubator or what it consists of

No unnecessary and old refrigerator needs to be thrown into a landfill, you can make an incubator out of it for the withdrawal of poultry.

The old freezer should be removed from the refrigerator. When using an incubator, you will need a network connection of 220 V.

To design the device, you will need the following parts: an electrocontact thermometer, a KR-6 relay, or you can take any other models, lamps.

The power of resistance of the coil should not exceed 1 watt. The assembled structure must be connected together with the lamps to the network. Incubator lamps are used L1, L2, L3, L4, which maintain the temperature up to 37 degrees. Lamp L5 equally heats all eggs located in the incubator, and also maintains optimum humidity.

The used coil opens the contacts KP2, and when the temperature in the incubator decreases, the process repeats. After the first use of the incubator, it is necessary to maintain the temperature mode with several lamps on all the time.

Made fixture should not consume more than 40 watts of power.

When designing the incubator, you can use both natural air circulation and artificial air.

Eggs located in the incubator can roll your hands, as well as using a special device.

There are situations that turn off electricity, so you can put a bowl of warm water in the incubator, which for some time will replace the lamp.

What can be made frame

The frame can be made of packaging from the TV. Inside it is reinforced with reinforcement or rivers. Inside the resulting frame can be positioned cartridges with lamps, not very high power, to maintain normal humidity and temperature. Porcelain cartridges are best suited.

To humidify the air, you can use a jar of water.

The distance between the lamp and the eggs should be 19 centimeters.

The distance between the bars can be about 15 centimeters.

To check the temperature in the incubator you can use ordinary thermometer.

The outer wall of the incubator should be removed, it must be covered with a material of dense fabric. To the side wall you need to attach the bath.

An 8 x 12 centimeter hole is made at the top of the incubator, to keep an eye on the temperature and for ventilation.

What should be the base of the incubator

At the base of the incubator, you need to make three small ventilation holes 1.5x1.5 cm in size. The amount of water needed per day is no more than half a circle. In the recesses between the slats put the eggs, but not tightly to each other, so that you can make a turn 180 degrees.

In order that there was an evaporation use lamps of 15 or 25 W. To make it easier for chicks to peck on a hard shell. do not turn off the evaporator.

When the eggs turn, they cool down, it takes two minutes. Throughout the period in the incubator should be maintained at a temperature of 38.5 degrees.

Incubator head

The upper body of the device must be covered with a dense mesh. Also with your own hands you need to mount two 40W bulbs. Bees are very good heat conductors, as well as monitor the optimal moisture regime. Can be used as a working hive, and no. In order for the bees not to penetrate, the beehive is wound with a very fine mesh and placed on the frame. The liner is placed directly above the net, where the first eggs are located, which are covered with a thick cloth.

What mode of operation should an incubator have?

Before starting the incubation period, it is necessary to check whether everything works in the incubation device for three days, as well as to establish the necessary temperature for the eggs.

The important points is to there was no overheating in the incubatorotherwise all chicks may die.

It is necessary to turn the eggs every three hours, because there is a difference between the two sides of 2 degrees.

The temperature regime in the incubator is observed depending on the types of poultry you have selected.

How to make a homemade incubator from the refrigerator.

We take the old refrigerator, remove from it all the excess - the heat exchanger, compressor, freezer, for the incubator we need only the body and the internal plastic trim from the refrigerator. If desired, the body outside can then be painted.

As heaters, we install conventional 220 V lamps inside the incubator casing. The number and power of light bulbs depends on the volume of the refrigerator

Important! To avoid local overheating of the eggs, the light bulbs should be placed at a distance of at least 15 - 20 cm from the eggs.

For medium-sized and large-sized refrigerators, 4 100-watt light bulbs are usually installed. You can place the light bulbs 2 on top, 2 on the bottom or all 4 on the bottom, the main thing is to ensure uniform heating of the eggs.

We connect the bulbs to the network through the thermostat. Connect the light bulbs in parallel, if one burns out, the rest will continue to work and maintain the temperature in the incubator.

Inside the incubator case, we install an ordinary room thermometer; in the process of incubation, it is necessary to periodically check the temperature readings on the thermostat and on the thermometer.

We install trays for eggs, trays can be made from welded metal mesh, from wooden slats or from plastic. The capacity of each tray 25 - 30 eggs.

Incubator from the refrigerator drawings.

In order not to turn each egg manually, you can make a lever device, the essence of his work is as follows. Each tray with eggs is fastened in the middle on the metal axis, to the side of the tray for a free connection is attached a strap coming out of the case.

To turn all the eggs together with the trays, it is enough to raise or lower the bar and fix.

As a result, the whole process of egg reversal is reduced to one simple movement.

At the bottom of the case, we install a fan for uniform distribution of warm air inside the incubator. You can use any 12 volt fan, for example, a cooler from the computer system unit.

The fan is connected to the network, respectively, through a 12 volt power supply unit; a charger from a mobile phone can be used as a power supply unit. The fan creates a stream of air, and all the eggs in the incubator warm up evenly.

During the incubation of eggs, a small amount of carbon dioxide accumulates in the incubator, so it is recommended to make several small ventilation holes with a diameter of not more than 1 cm in the case. A pair of holes in the lower and upper parts of the incubator will provide fresh air and carbon dioxide outflow.

At the bottom of the incubator it is necessary to install a small, wide container with water to maintain the humidity of the air.

When the incubator is assembled, you need to test its operation. We turn on the lamps, set up the thermostat, set the required temperature according to the incubation, for chicken eggs the temperature is 38 ° C.

When the incubator reaches the set temperature and the thermostat starts to periodically turn off the lamps, check the temperature near the trays with an accurate thermometer. In all places where the eggs will be located, the temperature should be uniformly the same, a deviation of no more than 0.5 degrees is allowed. If the temperature in different places is uneven, you need to change the location of the lamps or the fan, here you need to experiment and test empirically. The main thing is to achieve uniform heating of all eggs, without exception, a good percentage of successful incubation and hatching of chickens depends on it.

The advantages of such incubators

In general, the devices of their own production are not without virtues, among them are:

  • specialty stores offer a variety of models of automatic incubators with a lever system for turning eggs, but all of them are characterized by a rather high cost,
  • products from foam are often of low quality and not long service life,
  • factory models with automatic egg flipping are characterized by a limited number due to the special features of the one-story design of the slide mechanism,
  • often store-bought products for incubating poultry eggs have an unimportant design for turning eggs with a movable wire mesh,
  • many farmers have a domestic refrigerator that is out of time, which is a pity to throw out and can be used in poultry farming,
  • some manufacturers tried to start mass production of cheaper egg incubators that can be assembled by hand. However, the consumer was frightened away by the complexity of the instructions for collecting the lever system for flipping trays with testicles.

All these factors determine the wide popularity of incubators with an automatic mechanism for turning the incubation material, made by the hands of craftsmen from a box or a domestic refrigerator.

Incubator from the old refrigerator do it yourself

This method is considered fairly simple to make their own hands, and it uses quite a few craftsmen. In order to make an incubator - the presence of an old unfit or unnecessary refrigerator is obligatory. It does not matter what model it is or year of production, as long as it does not have mechanical damage to the walls and plating. It is important for us that it retains its insulating properties.

Tools and materials

  • refrigerator (without freezer),
  • thermostat,
  • 4 100 watt bulbs,
  • convenient trays or grids for placing eggs,
  • drill, tape, screwdrivers.

Step-by-step instruction

Such an incubator from the refrigerator, made by hand, will be in a horizontal position, of course, the door up. Therefore, we remove all shelves from the refrigerator, since they will not be needed.

  1. First, in the door of the refrigerator, you need to cut a small hole (about the size of a box of matches) for air circulation. Outside, the thermostat is attached to it with the help of an adhesive tape, and a temperature recording sensor is output through an inward hole.
  2. A sheet of plywood is installed on the back of the door, on which 4 cartridges with wiring are mounted and 100 W bulbs are screwed in. The connection diagram of the thermostat is attached. It makes a hole corresponding to the hole in the door. Yellow is the thermal sensor board, green is regulating resistors.
  3. At the bottom of the incubator, which is also the back wall of the former refrigerator, a small container with water is placed to humidify the air.
  4. Over this capacity with their own hands set the grid for eggs, so as not to get wet and be at some distance above the water.

Option number 2. Incubator from the refrigerator do-it-yourself instruction

In this method, you can use the refrigerator freezer as a hatchery incubator, which will significantly increase the survival rate of young. It will stand upright, as usual, and stands a refrigerator.

Tools and materials

  • old fridge
  • small pieces of hardboard,
  • metal rod 6 cm in diameter,
  • welding machine,
  • thermometer and thermistor,
  • spatula, glue, drill,
  • a fan with an engine and a tubular electric heater (if there are more than 50 eggs).

How to make an incubator out of the refrigerator with your own hands: step by step instructions

  1. The first thing you need to get rid of all kinds of shelves, cells and irregularities on the inner surface of the refrigerator, and close the cracks and openings tightly with pieces of fiberboard.
  2. After that you can do the placement of the thermometer with a thermostat. They are mounted in two holes made in the upper part of the case.
  3. Depending on the estimated number of eggs you need to calculate the number of slots. Trays can be made with your own hands from a frame welded from a metal rod and wrapped with a net. Which one doesn’t matter, some even use fishing. They are installed in place of the shelves of the refrigerator in the same grooves or fastened with screws to the walls. One of the options for manufacturing trays can be found in the video.
  4. For improved air circulation, you need to equip the fan. Its engine is mounted on the back wall, and a tubular electric heater is installed around its blades. Thus, it is achieved that the heat is evenly distributed throughout the entire volume of the incubator. The connection diagram of the thermostat is given above.
  5. A water tank is installed at the bottom to maintain the humidity level.

Scheme of the incubator from the refrigerator

What requirements must meet the homemade incubator

To carry out a competent assembly of a homemade incubator, it is necessary to know the requirements that poultry breeders place on it.

Until the time of hatching, the young should take about 10 days. During this period, eggs should be stored at a distance of 1 - 2 cm at a temperature of 37.3 - 38.6 degrees. The degree of humidity of the air at the moment when the first chick pecks the shell, should be 40 - 60%, in the process of hatching it rises to 80%. Moisture drops again before picking chicks.

Eggs can be placed in this unit in two ways. During the hatching of young geese and ducks, the angle of inclination should be 90 degrees. If the eggs are horizontal, they should be moved from the point of location at an angle of 180 degrees. During the day they need to be rotated at least 3 times. Before the very naklyov, namely a few days before hatching, the movement of eggs in trays should stop.

For a functional and durable domestic incubator, it is necessary to create an artificial ventilation system. By means of ventilation, the temperature and humidity levels are regulated. Ventilation speed should be 5-6 meters per second.

The incubator from the refrigerator, made according to its own drawings, is intended to become a device in which the incubation process repeats the natural one as much as possible.

The main conditions of incubation

The optimal temperature for quail output at home +37 degrees Celsius

Before proceeding to the description of the design, I would like to write a few lines about the conditions that need to be created in the incubator:

  • The number of days from bookmark to withdrawal should be 20–21 days.
  • The distance between the eggs in the incubator should be 10–20 mm.
  • It is necessary to provide a certain air temperature throughout the incubation, depending on the period.
  • Eggs in the cells are placed vertically, narrow side down, or spread horizontally. Placing the eggs vertically, trays for the convenience of their coup is better to set at an angle of 45 degrees.
  • When the eggs are horizontal, they should be turned over 180 degrees from the initial position. In automatic mode, the eggs are turned once an hour. In manual, at least three times a day, but preferably every 3 hours. Approximately three days before the end of the incubation, the eggs are turned over.
  • It is very important to create a good air circulation. The optimal is the circulation at a speed of 5 m / s.

Circulation of warm air inside the incubator will provide a fan

Horizontal way

Homemade horizontal incubator

Simple and common design that does not require much effort. Основное требование – это наличие холодильника с целой обшивкой и теплоизоляцией.

    • a refrigerator (if you have a freezer, you need to remove it),
    • 4 100 W bulbs
    • thermostat,
    • drill,
    • trays,
    • Scotch,
    • screwdriver.

Step by step description of the stages of work:

      • First of all, in the door we make a small hole (about 5x5 cm) for ventilation and start-up inside the sensors of the thermostat, which is mounted next to the hole on the tape. You can purchase a ready-made thermostat, or you can make it yourself. How to make a thermostat for the incubator with your own hands, this article tells in detail.
      • From the inside we fix a sheet of plywood, on which we install four bullets for bulbs. In plywood the same hole is cut as in the door.
      • At the bottom of the incubator is placed a container with water to humidify the air.
      • Over capacity install tray for eggs.

Vertical way

Homemade vertical incubator

      You will need:
      • fridge,
      • welding,
      • metal wire with a diameter of 6 mm,
      • sheets of hardboard,
      • thermistor, thermometer,
      • drill,
      • glue, spatula,
      • fan for additional ventilation and uniform heat distribution (if you plan to place more than 50 eggs, then you will need a fan.

Step by step description of the stages of work:

      • First of all, we get rid of shelves and irregularities inside the refrigerator and close the cracks arising from this gap using a sheet of fiberboard.
      • In the case of the incubator (above) make two holes in which we mount the thermostat and thermometer.
      • We make a framework for trays from a bar and tie it with a wire net. We fix trays in the case of the refrigerator.
      • We fasten a fan to the back wall with a heating element, in the role of which simple light bulbs or a tubular heater can act.
      • At the bottom of the incubator is also installed a container of water.

The main disadvantage of this design is the lack of automation. You have to turn a large number of eggs by hand. An incubator with an automatic egg flip has a more complex structure than the design described above, but at the same time it flips eggs without human intervention.

The tray automatically flip eggs in the incubator

And in the next article you will be able to get acquainted with the model range of the Blitz incubator.

Semi-automatic way

Incubator with semi-automatic egg flipping

The most difficult of the presented options, however allows to save time and gives the chance to increase productivity.

      • fridge,
      • self-tapping screws
      • trays,
      • metal racks,
      • a heating element,
      • fan,
      • metal axes, as many trays,
      • thermostat,
      • sinker,
      • plank with holes for the axis,
      • pin,
      • water tank
      • screwdriver and drill,
      • breathing tubes with a diameter of 30 mm 2 pcs.

Step by step description of the stages of work:

      • Section freezer grinder cut.
      • In the center of the side walls of the refrigerator with screws, fasten the strips with holes for the axis.
      • Through the middle of the trays pass through the axles, which are inserted into the slats in such a way that the trays are fixed between the slats.
      • Another metal strap is attached to the trays on the side closer to the front of the trays, combining them into a single structure. We attach the load to the lower part of the plank, and bring the upper one up through the pre-drilled hole. Now pulling this bar up or down, we turn all the trays at once. To fix the strap in the upper position, it is enough to drill a small hole in it, and fix it by inserting a cotter pin into it.
      • Mount the breathing tubes in one of the side walls, in the upper part and below, at a height of about 1/3 of the refrigerator.
      • In the lower part we have four 100 W lamps and a thermostat.
      • The fan is installed so that the air flow, passing through the bulbs heats the eggs.
      • At the bottom of the finished incubator installed water tank.

Egg incubation process

The semi-automatic production of an incubator will save you time and allow you to incubate a large number of eggs at once without additional labor costs.

From this video You will learn how to make an incubator from the refrigerator with your own hands:

Foam box

The best option to make a DIY foam incubator is to buy in specialized store foam thermal container suitable size. They are inexpensive - about 200−300 rubles.

After the main element of the future incubator has been acquired, it is necessary to carry out appropriate modifications of the thermal container so that it becomes an incubator:

  • A rectangular viewing opening of 30 by 20 cm in size is cut out in the lid, as well as two round openings with a diameter of 2 cm for ventilation and one with a diameter of 1 cm for the thermal sensor.
  • As heat sources use three incandescent bulbs with a capacity of 25 watts. Bulbs are fixed at the bottom of the incubation chamber.
  • Between the lamps there are two flat containers of water.
  • A 12-volt computer fan is also installed at the bottom of the camera.
  • The egg tray is made of a galvanized metal mesh with a mesh size of 15–25 cm. The bottom of the tray is lined with an extra mosquito net to prevent the hatching chicks from falling down to the bottom of the incubation chamber. Along the edge of the net, metal sides 8–10 cm high are soldered in order to prevent the hatching chicks from jumping out.

In this incubator, you can use a manual swivel mechanism. It is quite simple to assemble the simplest turning mechanism. For this purpose, in two opposite side walls at the level of the tray with the eggs, one is drilled through one through hole. Metal grommets are inserted into these holes.

On the inner side of the sleeve with metal corners fixed on both sides to the lattice. Outside, angled handles are attached to the sleeves for easy rotation.

As a result, the grid can be rotated around its axis in one direction or the other. Thereby, it is possible to produce a mechanical turn of the eggs that are on the grid, without opening the lid of the incubator.

From the old refrigerator

An out-of-life refrigerator can be a starting point for a very good one. almost professional incubator, designed for 100−120 and even more eggs.

Before you make the incubator out of the refrigerator, it is necessary to throw out all unnecessary from the old refrigerator, namely:

  • To remove the compressor and the freezer, as in the new device they will only occupy a useful place without carrying any functional load.
  • From above and below make two air vents.
  • At the bottom of the installed 12 volt fan.
  • Four incandescent bulbs of 25 W each are used as heating elements. Two light bulbs are mounted at the top of the camera, and two at the bottom.
  • At the very bottom there are two flat baths with water. Incandescent bulbs should be above them.
  • As trays for eggs use a galvanized mesh size of 15 to 25 mm. The second option is to use plastic boxes for fruit. In this case, the sides of the boxes are cut to a height of 5 cm.
  • All trays are turning, for this purpose, each tray is fixed on the longitudinal axis. In turn, each axis on the outside of the refrigerator is held together with a common vertical bar.

In order to make this incubator better, it is necessary to transfer it from the mechanical mode of turning the eggs to the automatic one. For the manufacture of self-made incubator with automatic turning of eggs It is necessary in the specialized shop to purchase the appropriate items, such as:

  • Thermostat unit.
  • Special trays of automatic egg turning.
  • Timer controlling the frequency of the coup.

With the help of this automation, you can assemble an incubator with a lead-out case that will be no worse than industrial designs. The rotation mode must be configured in accordance with one or another incubation mode, which directly depends on a particular breed of poultry.

We make an incubator from the refrigerator of the old sample

Many of us keep old, Soviet refrigerators in the old suburban areas, the workers, however, cannot be compared with modern models. It is time to get rid of the trash, turning it into agricultural utility!

The installation will be located on the back wall, the door to the ceiling, so immediately remove the shelves and other interfering elements from inside the refrigerator.

"Lying" incubator from the old refrigerator

The main condition for the manufacture of an incubator from a refrigerator is the integrity of the walls of the unit, since it is necessary to create a stable microclimate inside the future incubator and maintain a certain temperature, humidity level, etc.

Benefits

Let us list the main list of advantages enjoyed by incubators independently created from refrigeration units.

  1. Spaciousness. To buy a household incubator in a store, which has about the same capacity as a unit made from a refrigerator, you need to spend a large amount. And considering the fact that many of us have old refrigerators doing nothing since Soviet times, the independent creation of a device can do almost free of charge.
  2. Creating the perfect microclimate. The fact is that the design of the refrigerator and the material of its body are ideal for creating and maintaining the microclimate needed by chickens.
  3. Ease of device creation. It is a pleasure to work with old refrigerators, it is simply impossible not to appreciate the material flexibility.

Learning to make incubators from the refrigerator should be due to the large list of benefits.

Necessary materials

So, in order to independently assemble the incubation device from the old refrigerator, we will need the following materials:

  • fridge,
  • plastic trays for eggs, commensurate with the chamber,
  • thermoregulation device

Incubator thermostat

Getting Started

We put the old refrigerator in a horizontal position and remove everything superfluous from the inside. Then, with the help of cleaning agents and disinfecting fluids, we process the housing from the inside, as well as from the outside, to prevent the development of pathogenic bacteria next to the future chicks.

It is very important to thoroughly clean the refrigerator before turning it into an incubator.

Thoroughly clean every gap from dirt, the refrigerator should shine. According to statistics, it is poorly cleaned dirt and the microorganisms living in it becomes the main cause of the mass mortality of chicks in the incubators.

We cut a hole in the door of the unit through which the thermoregulation device of your choice with a sensor will crawl through. Then, gently insert the device into the hole and secure it with the outer and inner sides with adhesive tape.

Thermostat with sensor

We take the prepared sheet of plywood and install 4 cartridges on it, to which electrical wires are pulled, and then we twist all four lamps with a capacity of 100 watts. After that, we install the assembled heating and lighting device on the inside of the refrigerator door, securing the plywood panel securely to the body of the future incubator.

Prepare the air humidification system. It will consist of a plastic pallet, which we will install on the back wall of the refrigerator (it is now the bottom of the incubator). Pour clean water inside the container and install inside.

What does a water tank look like suitable for a homemade incubator?

Slightly above the installed pallet, install a metal grid on which you install plastic egg boxes. It is necessary that the eggs were at some distance from the water and not over-humidified.

A feature of this homemade installation is the lack of an automatic egg turning system. In order not to get confused, which of the batches you have already scammed, make notes on the boxes. You can use a pen or washable marker for this.

If your incubator is not equipped with an automatic and semi-automatic egg reversal, you will have to control this process yourself. To do everything right, read our article. Why do I need to turn the eggs? How often to turn over?

Making a vertical incubator from the refrigerator

The unit resulting from the execution of this instruction is obtained by standing upright. This design is more convenient than horizontal, as it leaves the possibility to make a window for observing the hatching birds.

Vertical incubator out of the fridge

Required materials

Let us proceed to the listing of materials and tools that will be useful to us in the process of turning a refrigeration unit into an incubation unit:

  • old fridge
  • sheet fiberboard,
  • temperature measuring device
  • thermistor,
  • egg trays
  • glue,
  • an engine-equipped fan with a tubular electric heater design,
  • putty knife,

Incubator materials from the fridge

In the manufacture of an incubator from the refrigerator without a drill can not do

Welding machine

Let's start work

We extract from the inside of the future incubator everything superfluous:

The first stage is the removal of unnecessary parts from the refrigerator.

After removing all unnecessary parts of the refrigerator, proceed to cleaning the case inside and out. As mentioned above, at the beginning we wash the case with detergents, then with antiseptics. After washing and processing each slit, go to the second stage.

Let us proceed to the alignment of internal and external damage to the housing of the old refrigeration device. To do this, carefully examine the surface of the walls and every hole found we fill up with a piece of fiberboard, carefully sticking it over the damage.

Pieces of hardboard suitable for sealing damage

In the most damaged areas, in addition to glueing DVP to the surface, additionally use self-tapping screws so that a piece of the panel does not fall off at the most crucial and unexpected moment.

Making trays. Calculate the number of eggs approximately planned to be placed inside the future incubator. Based on the received figure, let's proceed to the purchase or manufacture of boxes. How to make boxes, read further in the article.

Shelves inside a homemade incubator

Equip ventilation. In order to constantly circulate air through the incubator, it is necessary to mount the fan on the back wall of the refrigerator, the motor part is installed outside. Along the perimeter of the front door of the refrigerator, it is necessary to make several holes through which air will penetrate into the unit.

As a fan for a homemade incubator, parts from an old computer will do.

The heating queue. Around the fan blades, on the back of the refrigerator, carefully place the tubular heating element. This position near the ventilation system will allow the heat to be distributed evenly in the incubator, capturing even remote corners.

Install the water tank to the bottom of the refrigerator. Since the humidity level needs to be kept stable for a long period of time, it is better to adapt the device as a pallet as deep as a tray for cats.

Tray for cats is suitable as a pallet

The quality of the water with which the pan is filled must be at the level. It is not necessary to use filtered liquid, ordinary tap water will do, the main thing is to be clean.

The disadvantage of this type of incubator is exactly the same as the previous one: the lack of automatic turning of the eggs. You will have to do it again manually, carefully tidying up the houses of non-hatched chicks. It is best to work with gloves.

Vertical incubator out of the fridge with semi-automatic egg turning

This type of incubator from a refrigeration unit is more difficult to implement than the previous ones, however, it can significantly reduce the time spent on self-reversal of eggs. No, the incubator will not do it on its own, however, it will be possible to turn the cells forward in one motion.

The principle of manufacturing is similar to the previously described method, however, there are significant differences in the installation of additional mechanisms. You will have to spend a little more time, but the result will make you feel real pleasure.

Drawing vertical incubator from the refrigerator, the direction of circulation of air flow

Materials and tools

  • unnecessary refrigerator
  • thermoregulatory element
  • pin,
  • trays for eggs made of plastic or metal
  • axles made of metal, 8-9 millimeters in diameter,
  • a heating element,

Incubator Heating Element

Getting Started

Cut inside the section separating the freezing and refrigerating chambers, if available in the design. We remove from the inside all the excess and close the gap, by analogy with the instructions for the second and first methods.

We process the body of the future semi-automatic incubator with cleaning agents and antiseptics, wipe dry and prepare to install the main parts.

Option of vertical incubator from the fridge

We find the center of the front door and the rear wall of the refrigeration unit, and on this level we install the racks, which we fix in the device case with the help of metal screws. In the racks we make holes at the level of the shelves.

Screws for metal

In each cellular tray for eggs we insert an axis from metal which diameter will make about 8-9 millimeters. Обеими концами устанавливаем ость в стойки, получая ровные ряды ящиков между ними.

Этап сбора вертикального инкубатора

We fasten a metal strip on the egg boxes using screws as fasteners. The gap must be at least two millimeters. From the bottom side of the plank it is necessary to hang a five hundred gram weight, in the role of which absolutely any heavy object can act. A pin is attached to the free part of the plank from below, which plays the role of a fuse, preventing it from going inside due to the pressure of the suspended load.

Fastening the slat to the trays, setting the load

At the top of the incubator, the bar extends outside the enclosure. To do this, drill a hole in the top of the refrigerator.

We install the breathing tubes into the side of the refrigerator, drilling the corresponding holes in the body, top and bottom, each time approximately at the level of the third part of the height.

We equip lighting and heat by installing three lamps on the back of the refrigerator, with a capacity of about 100 watts. According to the scheme, we connect to them a thermostatic device.

Installation of incubator elements from the old refrigerator

Ventilation in the form of parts from a computer or a small domestic fan is installed so that the air must pass through the heating elements.

Fill the pan with water and place it on the bottom of the incubator.

Everything, the semi-automatic incubator is ready! To turn the eggs, you only need to raise the bar up, and then release it, securing the pin into another hole. During the implementation of this procedure, trays attached to it bend in the other direction, changing the position of the embryo inside the egg, as well as substituting the other side for heating. So you will save a lot of time on hand laying eggs and get high-quality and healthy feathered offspring.

Removal of chicks in a homemade incubator

However, we all understand that a semi-automatic incubator is not yet an ideal. Therefore, we advise you not to make a decision before reading the following instructions, with which you can make a fully automatic incubator!

We make an incubator out of the fridge with an automatic egg turning device

Carefully study this original method of manufacturing an incubator from an old refrigerator, which will turn the eggs inside of itself automatically. Then you will have to take only minimal participation in the artificial incubation of eggs, which consists in:

  • laying eggs
  • pouring water into the pan,
  • rearing chicks.

We build the unit

My refrigerator and remove from it all unnecessary. Since the heating elements in this kind of homemade incubator will be at the level of the freezer, we cut out four holes in the plastic segment separating it from the main refrigeration unit, equal in diameter to small fans, remove all shelves, cells, grids and other components to the refrigerator.

What will be the incubator

We make a window in front of the fridge below. It can be any size you want. Saw the required size of the hole in the refrigerator and handle the incision site.

Install a frame made of aluminum or wood into the cut-out hole, it is better to give preference to the first material, since it is more durable. At the same time, install a glass or plastic plate inside the frame. Cover the joint slots with a sealant to prevent the passage of cold air through the slots inside the incubator. The window is ready. Now you can observe what happens to the eggs during the incubation process, without opening the refrigerator door and without breaking the microclimate.

Warm the front surface of the refrigerator with heat-reflecting material, especially carefully around a homemade window. Foil insulation is suitable. This is necessary so that the heat produced by the lamps does not pass through the thin parts of the body to the outside, but is reflected inwards.

Warm from the inside the individual parts of the refrigerator using heat-reflecting material

We master a metal frame for the installation of grids, on which we later put trays with eggs. To do this, we weld thin profile pipes together and fasten them to the bottom of the refrigerator. We fasten metal lattices above each other.

Mastering the mechanism responsible for turning. The role of the motor drive is played by parts from an ordinary bicycle - chain sprocket. They are attached to a metal sheet welded to the side of the profile frame of the device. Driven sprocket drive is welded to the outer side of the sheet, the leading is mounted on the pin.

Limit switches will act as elements that supply the system with electricity. As soon as the device reaches the end position, the power will stop flowing and the system will stop working.

The motor is set in motion with a pair of timers set so that work resumes every 6 hours.

The motor is driven every six hours with two timers.

The thermostat is installed at the level of one third of the entire height of the refrigerator. It is mounted and fixed in the case. Heating elements in the form of lamps are installed in the place of the former freezer. The heating is switched off and off with the help of a regulator on the relay.

Ventilation set as follows. In the holes we cut in the plastic segment that separates the freezer compartment from the cooling compartment, we install the fans connected to electricity and fasten them to the surface with metal adhesive tape.

So, our automatic incubator is ready! Now you can relax and truly enjoy the process of breeding birds!

How to make a egg cell yourself

The easiest way is to buy plastic cellular trays, since they are designed for an incubator and do not have to waste time on their production.

Scheme of self-fabricated mesh for eggs

However, if you decide to make them yourself, you will need the following materials:

  • metal mesh,
  • wooden bars, 4 pieces,
  • two wooden corners,
  • nails.

How large the mesh will be depends on the size of the cooling device you have chosen as the basis for your future incubator. However, there are recommendations regarding the size of the metal mesh cells, depending on the type of bird that is displayed inside the device. We invite you to familiarize yourself with them in the table below.

As you can see, the size of the cell varies depending on the size of the future egg, which is placed inside.

Getting to the self-production of cells

  1. Measuring the inner perimeter of the refrigerator, we connect the existing bars of small thickness into the frame, securing the joints with nails.
  2. On the resulting frame from the bottom we stretch the net, so that it sits tight and does not bend. Fix the grid with nails.
  3. We lay corners for eggs on each side and fasten them with glue and wood screws.

Homemade egg tray

If you do not know how to measure the perimeter of the inside of the refrigerator, simply assemble the frame on top of the grids that were previously removed as unnecessary, because you’ll put the baskets in their place.

Here is a table of the pros and cons of self-fabricating cells:

  • serious savings on the purchase of specialized cells,
  • possibility of self-production from scrap materials,
  • ease of use and installation
  • ease of cleaning cells.
  • erasing and sagging over time
  • gradual loosening of the cell mounts due to high humidity,
  • rapid deformation of wooden frames,
  • If the net is too tight, it may burst and the eggs will be damaged.

Tray for wooden incubator

As you can see, it is better to give preference to a purchased plastic box. However, if you are still an adherent of completely independent production of the incubator, replace all wooden elements in the self-made cell with metal rods or tubes, and nails with a welding machine, in order to minimize the negative effects of humidity inside the incubator and extend the service life of the manufactured part.

An interesting piece of advice: if you have a lot of egg cartons, use them inside the incubator, placing them on shelves made from an iron grid. Yes, such cells often have to be thrown out and inserted into new ones, but this is a really convenient option for the first time.

Incubator windows

It is possible to make a window in the case of an incubator made of an unnecessary refrigerator in each of the methods described in this article. Only the place of cutting out the opening for the frame and glass, as well as the materials used will be different.

We list the most popular materials that are suitable for the manufacture of a window frame in the body of the refrigerator:

The frame for the window in the incubator can be made of wood and aluminum

You can easily understand why it is these two names that are preferred. It's simple, easy to work with. However, aluminum is much easier to wash and process with antiseptics than wood, so give preference to it.

You can also look at how eggs develop through two materials:

These options are equally suitable for installation in an incubator from the refrigerator, but still, the glass has a special advantage - strength. Since the assembled unit will be operated for years, make an investment in the future and install a glass window.

Electrical wiring

Additionally, it is not necessary to isolate the wiring inside the incubator, as in most designs they do not interact directly with newborn chicks or other possible hazards. However, if you are worried, you can skip the wires inside the cuts of a regular rubber hose. In such protection there is a high proportion of practicality: the probability of accidental damage to the wires is reduced by an awkward movement of the hand or as a result of another incident.

Where to get the details

Most farmers have one common trait - the rejection of the accumulation of unnecessary trash. Of course, everything in the household will come in handy, but only a sloppy person will do business in disarray. Therefore, at hand may not be any old refrigerator or metal grills. Do not think that buying all the necessary materials will cost you a pretty penny. On the contrary, many people dream of attaching the trash accumulated over the years and get at least a minimal profit for it.

Ask for help from your neighbors and soon collect the necessary details. If something is still missing, look at the flea-market sites and solve the problem by itself.

Kits for Automatic Incubator

For those who do not consider themselves to be a technical genius, and will not be able to repeat the installation of the automatic system even according to the attached scheme, we have an interesting hint. Many agricultural stores sell kits for automatic incubators, which contain the following essential elements.

  1. A tray with egg cells, equipped with an engine for automatic turning, powered from a 220V network. If you buy several such trays, then each of them will turn over in the refrigerator body without requiring your intervention at all.
  2. A timer that activates the motor every given period of time (for example, every six hours).
  3. Thermostat with sensor and digital panel. With his help, you will always see if the future chicks are warm enough inside their first dwelling.

Mandatory components of the kit for automatic incubator

Depending on the cost of the kit, it is supplemented by a ventilation system, additional trays, etc. The kit often provides additional devices that are useful to poultry farmers, for example, an ovoscope, with which it is checked whether the fruit continues to develop inside the egg.

Let's sum up

So, now you know how to independently assemble the following types of incubators on the basis of the old refrigerator:

  • ordinary, requiring human intervention,
  • semi-automatic, through which the turning is carried out in one motion,
  • automatic incubator, requiring only periodic pouring of water.

Of course, to recreate each of the described units requires a certain skill, building knowledge and experience. The work is not hard, but painstaking and meticulous, requiring the assiduity and perseverance of the master. It is possible that in the process of installation will have to redo some parts and mechanisms.

Original execution of the idea

The important point is the quality of the selected parts. In spite of the fact that you will find many of them in the “ejection” store, follow the strength of the materials. Completely worn can not be used, because the sense of them will not. Breakdown will occur in a few days of use and not only your work will disappear, but also a whole brood of feathered babies.

If there was no refrigerator on hand, do not despair. Options to make an incubator with your own hands a great many. To get acquainted with them, read our article. Step-by-step instructions for creating incubators from a cardboard box and foam plastic, requirements for incubators, determining the optimal size of the incubator.

We believe in your success! Carefully follow the instructions, review the schemes presented in the article and then you will succeed.

Step-by-step instruction

Such an incubator from the refrigerator, made by hand, will be in a horizontal position, of course, the door up. Therefore, we remove all shelves from the refrigerator, since they will not be needed.

  • First, in the door of the refrigerator, you need to cut a small hole (about the size of a box of matches) for air circulation. Outside, the thermostat is attached to it with the help of an adhesive tape, and a temperature recording sensor is output through an inward hole.
  • A sheet of plywood is installed on the back of the door, on which 4 cartridges with wiring are mounted and 100 W bulbs are screwed in. The connection diagram of the thermostat is attached. It makes a hole corresponding to the hole in the door.

  • At the bottom of the incubator, which is also the back wall of the former refrigerator, a small container with water is placed to humidify the air.
  • Over this capacity with their own hands set the grid for eggs, so as not to get wet and be at some distance above the water.

In order not to get confused when and which eggs to turn, the only option is to make a mark with a marker or marker. It is also worth remembering that depending on the length of the incubation period and the type of eggs, certain conditions must be observed. For example, cool eggs, do not exceed the humidity and so on.

Homemade horizontal incubator

In this method, you can use the refrigerator freezer as a hatchery incubator, which will significantly increase the survival rate of young. It will stand upright, as usual, and stands a refrigerator.
