Chickens carry small eggs: reasons for what to do


If mini-testicles in nests appear without apparent regularity, there is no cause for concern, but regular deviations from the standard need to be corrected. There may be several reasons why such problems occur in the body. Among the most common - hormonal failure and the age of the bird.

Age factor

At the end of sexual formation, the egg of pullets does not reach adult size. This is due to a lag in development: with full-bodied yolk, the protein layer is not yet fully formed. Despite the fact that this zest enhances the taste of the product, its mass differs from the average in the direction of reduction.

Breed features

A variety of chickens can affect products: birds can give both miniature-sized eggs and delight their owners with large-caliber samples. For the White Sultanka, the weight will be 45 grams, for Cochin - 55 grams, while the Leggorn, Isa-Brown, Minorca, Hisex-Brown, Pushkin, High-line, Russian White Chicken breeds put 65, 70 and even 80 - gram copies.

Hormonal disbalance

Egg ripening in the womb happens 1 time per day. During this period, the egg cell passes through the reproductive system of the bird, overgrown with yolk and protein, film and shells.

Responsibility for this process lies with the hormone system of the hen. If it fails, the egg will not be able to develop to full size, and a smaller product will be formed. Under similar circumstances, the yolk may be completely absent.

Metamorphosis of hormonal background due to a number of reasons that depend on the following factors:

  • abrupt diet change,
  • aggressive noise environment.

With prolonged fasting, hormonal disruptions are also observed.

Foreign objects in the oviduct

Layers - creatures are very curious, which leads to the appearance of foreign objects in the internal genital tract. Most often inside inquisitive birds can be found:

  • litter parts,
  • feathers,
  • pebbles
  • small pieces of steel.

They enter the body of the bird through the cloaca, and during passage through the organs of the reproductive system, the hen's organism is perceived by the body as the yolk. A further reaction of the reproductive system resembles the process of egg formation: a protein layer and a shell begin to form around the foreign body. As a result, a pseudo-product of small size appears.

Inflammatory processes in the oviduct

Inflammation of the oviduct - salpingitis is often found during the period of active clutch. Symptomatology of the disease manifests itself quite brightly through the following symptoms:

  • decrease in egg size,
  • the layer stops running indefinitely.

In addition, the birds are actively gaining weight.

Ways to solve the problem

After finding out the reasons explaining why the chicken carries small eggs, it is necessary to proceed to treatment and improve the situation.

Important. The first step is to check the age of the bird. If she has not reached 6 months or is in the molting stage, you should not panic. You need to wait for the final puberty or update of the plumage of the hen.

If none of these factors explains the current anomaly, it is advisable to apply the following methods:

  1. Universal way. To do for 21 days fortified menu, complementing the usual diet of 20 mg of potassium iodide per 1 individual.
  2. In the presence of foreign objects: balance the feed on protein-carbohydrate components and carry out cleaning of the house.
  3. Inflammatory diseases of layers: isolate diseased birds from the herd and seek help from a veterinarian.
  4. Hormonal disorders: enhance nutrition through the addition of vitamins D and E, check the room for drafts.
  5. Preventive measures:
  • keep the coop clean
  • change litter regularly,
  • light mode - at least 18 hours. If it gets dark early, increase the length of daylight due to the use of artificial lighting,
  • temperature conditions - year-round from 15 to 21 ° C. If necessary, you can increase to 23 ° C,
  • ration - it is advisable to always add chopped green mass and premixes to dry chicken food,
  • provide space for walking and set comfortable roost for sleeping.

In addition, it is necessary to carry out regular disinfection of the room, at least 1 time in 2 months, as well as provide the birds with comfortable sleeping roosts and a spacious walking area.

Why do chickens carry small eggs or how many eggs a day can a chicken carry?

Answers to these questions excite every beginning poultry breeder. With respect for the standards of care and the provision of proper conditions for birds to be kept, the problem of small eggs will bypass the caring owner.

When and why do chicken eggs shrink

The chemical composition of the egg is a unique product - it contains 11 essential vitamins, 16 elements from the periodic table and 7 essential amino acids. All ingredients are balanced in such a way that they provide almost 100% digestibility, providing the human body with beneficial fatty acids and high-quality protein.

If small eggs appear rarely, do not focus on this.

In the event that small eggs appear sporadically in the poultry farmer's basket, and the grinding is not regular, then it may not be worthwhile to pay particular attention to what happened. However, when day-to-day chickens carry an egg the size of a quail, you should determine the cause of the pathology and eliminate it.

Prerequisites for egg shredding

The stable appearance of eggs in the hen-coop below the standard weight and size can be caused both by external causes and by the characteristics of the concrete hens. The most obvious reasons are:

  • too early onset of egg laying,
  • breed specific features
  • hormonal hormone at the hen,
  • getting into the oviduct of a foreign object,
  • internal inflammatory process.

The cause of egg droppings may be a hormonal imbalance in the hen

Inflammatory process in the oviduct of the layer

Salpingitis - inflammation of the poultry oviduct - a disease characteristic of chickens during active egg-laying. Symptoms of salpingitis appear quite clearly:

  • eggs decrease in size
  • laying stops indefinitely
  • layer is actively gaining weight.

The first and most prominent symptom that may indicate salpingitis is increased fat

The sick layer looks depressed, it loses its appetite, and there are violations of the stool. A complication of salpingitis is the loss of the oviduct - in this case, the chicken ceases to carry the eggs completely. Inflammation in most cases is caused by an excessive amount of protein in the diet of the bird and a lack of necessary vitamins.

Fish oil is rich in vitamin A

At the slightest suspicion that laying small eggs may be associated precisely with the presence of the inflammatory process in the oviduct, it is necessary to adjust the diet of the hen, add vitamin ingredients (A, D and E). If necessary, medications are used - intramuscular injections of synestrol and watering of pituitrin. Exact advice on the dosage of drugs should be given by a veterinarian.

As a prophylactic agent that improves the immunity of poultry, the addition of potassium iodide (3 mg per head) to the feed is welcomed. To conduct the recovery of the hens should be for 20 days. At the same time it is necessary to use a balanced feed, regulation of the light mode.

It is especially important to carry out preventive measures for pullets that have just entered the phase of puberty and immediately after the end of the winter period.

Need to know! Lack of treatment for salpingitis of the neglected form can not only lead to the death of the hen, but can also contribute to the extermination of the entire chicken population.

How to solve the problem of the appearance of small eggs

If in a hen house, well-fed eggs began to appear over and over again, it is necessary to take measures to solve this problem. Firstly, it is necessary to determine the cause of this phenomenon.

In cases where small eggs are carried by a young hen, the poultry farmer should wait for the age of the bird at 5.5-6 months. Usually, by the six months of age, the internal paths of the hens develop sufficiently so that the eggs obtained are of a size characteristic of the breed of hens.

Egg adult and pullets in comparison

Sometimes poultry farmers stimulate early laying by increasing daylight hours. With the help of manipulations with lighting in the chicken coop, it is possible to reduce the period of the onset of puberty and get the first clutch 10-14 days earlier than the set moment. Such actions are able to give a positive result, pullet starts to lay eggs before the deadline.

However, it must be borne in mind that the artificial reduction of the period of sexual maturity will lead to the fact that the time of laying of small eggs will be delayed, besides, the hen can get considerable health problems.

If a small egg appears due to the penetration of foreign objects into the internal pathways of the laying hen or a sudden hormonal breakdown, then it is usually one-off. It is important for the poultry breeder to watch the hen for several days, whose eggs are found to be reduced in size, taking steps to provide the chicken with balanced food and a clean habitat. As a rule, after a few days the situation normalizes and small eggs disappear.

If a decrease in egg production is associated with inflammatory processes, you should contact your veterinarian.

The situation is more difficult if the decrease in productivity and the appearance of small eggs is associated with inflammatory diseases of layers or prolonged failure of ovulation. In such cases, all that the breeder can do is to provide the livestock with good nutrition, regular walking and a clean, comfortable roost. Treatment issues should be entrusted to a veterinarian, who will be able to prescribe adequate treatment.

Why do not chickens rush? This question arises from many farmers. In this article, we consider the main content errors affecting the productivity of layers.

Causes of reduced egg size

The owner of the estate, who noticed a steady decrease in the size of the eggs laid, must find out what the cause of this phenomenon is. Despite the fact that most of them are not serious, and almost do not require human intervention, several causes can lead to the death of the bird.

There are several reasons why chickens carry small eggs.

The most common are:

  • Age. Young chickens, just started egg-laying, are very tasty, with a large yolk, but small in size eggs. Until the bird reaches the age of nine months, the size of the eggs may differ from that of the breed. Older chickens can also carry small eggs, as the reproductive system wears out.
  • Breed. The size of eggs laid by the hen is more dependent on the breed of the bird, and not on its size. Small Minorca or small Kuchinsky jubilee carry large eggs, and the huge Brahma or Cochinchina - relatively small.
  • Metabolism. All metabolic processes in the body of the bird occur, normally, according to physiology. If the production of a hormone is impaired, then it causes a malfunction in the body, which directly affects egg production. As a rule, when hormonal disorders, the egg is not only small in size, without yolk.
  • Foreign body. The chicken oviduct is the place where the egg is formed, so if a foreign object gets into the oviduct, the chicken recognizes it as a yolk. As a result, the shell is formed either around the object that has entered the oviduct or near it. The main sign of a foreign body entering the oviduct is getting small eggs that do not contain yolk from a sick chicken.
  • Inflammation. Inflammatory diseases of the oviduct disrupt the normal formation of eggs and lead to a sharp decrease in egg production.
The size of the eggs depends on the breed of chicken.

Important! In addition to getting small eggs from a diseased bird, inflammation leads to the loss of the oviduct and the death of chickens.


Inflammatory processes within the body of the bird can also often influence the size of the eggs produced. Adult individuals that brought eggs of normal size and suddenly they began to carry small eggs, then perhaps the reason is inflammation of the oviduct canal. The causes of inflammation vary from poor sanitary standards in the hen house to unbalanced feed. Therefore, for the prevention of used sanitary treatment of the premises, changing the litter, providing the necessary temperature and light conditions. Oviduct inflammation can be managed using washing, for example, with warm saline: 18 grams of salt per cup of water in the morning and evening for 3 consecutive days. After that use an enema once a day. Enema is carried out in the absence of eggs inside the bird. In addition to the enema use drugs such as Trichopolum, it is an antimicrobial agent. The required amount of the drug is crushed, diluted with water and poured into the beak. Revise the diet, so that it has everything you need, you can include water-soluble vitamins. If after the events held, the bird continues to carry small eggs, it is necessary to consult with a veterinary specialist.
