The color of egg yolk can determine the health of the chicken - it is more or less intense yellow color. But sometimes it happens that chickens start laying eggs with green yolks. Whether it is a deviation from the norm, whether it is possible to eat such products for food and what should be done to eliminate this problem - the answers to these questions in our article will be useful not only for poultry houses, but also for housewives who are faced with the task of choosing quality products.
What determines the color of the yolk
The color of egg yolk depends on several factors, including:
- Conditions of poultry. If the chicken is kept in the household, walks in the wild and, apart from absorbing grain, has the ability to be bred and to find various bugs and worms in the ground, then the yolks of eggs laid by it will be more saturated yellow-orange. But when the norms of keeping birds are violated, at which they are indoors for 24 hours, do not have the opportunity to move well and do not receive enough UV light, then the yolks of the testicles of such chickens will have a pale yellow color.
- Seasonality. Sometimes the color of yolks depends on seasonal changes: in winter, it may be paler from fewer fresh vegetable feed and insufficient intake of ultraviolet radiation.
- The composition of the feed. If the chicken organism sufficiently receives all the nutrients and vitamins, then the yolks in the eggs will be painted in a more saturated color.
Important! Eggs with bright orange yolks are in high demand among the population, so unscrupulous producers add artificial pigments to feed for layers, which can have a detrimental effect on the health of consumers. Therefore, if the yolks of eggs purchased have an unnaturally bright color, it is better to refrain from acquiring them.Video: chicken yolk colors
What color should egg yolks be?
Quality eggs from healthy layers can be with yolks of different shades of yellow, as this depends on the amount of carotenoids in food. These antioxidants contribute to the formation of vitamin A, which makes these products valuable to our body.

Carotenoids are part of the following components of the combined feed:
- yellow corn varieties;
- carrot;
- dog-rose fruit;
- red paprika;
- tomatoes;
- green grass or substitutes (alfalfa grass meal).
Also, dark yolks indicate the content of fatty acids (Omega-3) and xanthophylls in them. If only grain dominates in the poultry diet, then the egg yolks will be pale, with lower nutritional value. Consequently, the better and better the nutrition of the bird, the richer the color of egg yolks, and the more valuable substances they contain.
Is it possible to eat eggs with green yolks
If you find that your chickens began to carry eggs with green content, or you purchased such eggs in the store, then it is best to refrain from eating these products.
Did you know? If you cook scrambled eggs from one ostrich egg, then it will have the same volume as scrambled eggs from 25 chicken eggs.
What if the chickens began to carry eggs with green yolk
First you need to trace whether all chickens began to give eggs with this pathology or only individual individuals. Then it is advisable to give such eggs for research. 
To get an accurate conclusion about the causes of this phenomenon, it is best to contact the laboratory of veterinary and sanitary examination.
Painting the yolks in a green shade may indicate the following factors:Reasons for rejection
- Chickens are given food with green colored pigments.
- Viral diseases of chickens.
- Old age of layers.
- Failure to store the eggs or damage to their shells, due to which harmful substances are ingested.
- Infection of eggs with putrid aerobic bacilli.

In the latter case, green rot occurs in the product, caused by the various groups of bacteria Pseudomonas. Typically, these bacteria are in the traces of chicken droppings left on the egg shell. 
With increased humidity from the surface of the shell, putrefactive bacilli freely penetrate into the eggs and begin to multiply rapidly there, emitting greenish substances. Also, a green color may appear due to the development of Staph aureus inside the bacilli.
How to bring the yolk back to normal
Here are some suggestions for eliminating the causes of this anomaly:
- If it is established that the cause of the unnatural color of the yolk was nutrition, which included green color pigments, it is advisable to revise the diet of hens and eliminate such feed.
- In case of viral diseases and other illnesses, it is necessary to consult a veterinary specialist, who will determine which virus affected the birds, and prescribe a course of a suitable antibiotic.

- If the age of the layer became the cause of the green yolk, then this problem can be eliminated by the planned replacement of older individuals with younger ones.
- It is important to observe the terms and conditions of storage of the product: in a dark, dry, cool place, at a constant temperature from 0 to + 20 ° ะก, avoiding sharp temperature differences. Shelf life - 25 days.
Prevention of diseases affecting the color of the yolk
Here are some preventive measures to prevent this pathology in the hens:
- Vaccination. With the threat of the spread of viral diseases, it is important to give the birds regular vaccinations with a live attenuated vaccine, after which the vaccinated chickens will have active immunity.
- Hard sanitation. To avoid viral chickens, prevent infection of eggs by putrefactive bacteria and microorganisms, as well as their spread inside the chicken coop, you must strictly adhere to the rules for collecting eggs, their preservation and sanitary and hygienic requirements provided for in the preparation.

- The right conditions of detention. We can not allow a large area contained a large number of birds. The room where chickens are kept should be spacious enough and well ventilated.
- Timely disposal of dead individuals. Dead birds need to burn or bury deep, peppered them with quicklime.
Important! Required add in feed layers of fine gravel so that its muscular stomach can better grind them.
Food rules for high quality egg production
To increase egg production, you need to know some rules for feeding chickens:
- Regular and uniform feeding. Poultry should be fed twice a day: in the morning and in the evening. Morning feeding is carried out immediately after the awakening of the birds - they give a wet mash (boiled potatoes mixed with ground grain, bran, crushed eggshell, salt and kitchen waste). In the evening, pets need to feed whole grains an hour before bedtime. Every evening feeding, it is desirable to give a grain of a different type (today - oats, tomorrow - barley, the day after tomorrow - wheat, etc.).
We recommend reading about how to make feed for laying hens, how much feed you need to feed a laying hen per day, whether you can add bread to the diet of chickens, as well as what vitamins they need for egg production.
- Feed quality. Better egg production can be achieved only if the chicken gets with the full range of nutrients: proteins, mineral salts, carbohydrates, fats, vitamins.
They are obtained from cereals, wheat germ, yeast, bran, greens, root crops, meat waste, cottage cheese, as well as vitamin and mineral supplements. - Feeding rates. It is important to correctly calculate the norms of feed consumption, taking into account the actual or estimated productivity of the hens: the greater the live weight of the chicken and its egg production, the more feed it will consume. For example, if a chicken weighing 1.8 kg carries 100 eggs per year, the feed consumption for it per day should be no more than 125 g. With more weight (2 kg) and the same egg-laying, the chicken will need 135 g already (further for every additional 250 g add 10 g feed). In addition, for every 30-35 eggs in excess of 100, the amount of feed is increased by 5 grams.
They are obtained from cereals, wheat germ, yeast, bran, greens, root crops, meat waste, cottage cheese, as well as vitamin and mineral supplements.Important! Feeding rates are influenced by seasonality and age of layers: in winter, the need for feed increases, and for young chickens more nutrients are needed.In conclusion, add - if you find a change in the color of chicken yolk to unnatural, then you must refrain from eating such a product for food and seek advice from a veterinarian.
Did you know? In the United States in 1910, a record was set for eating boiled eggs: a man ate 144 pieces at a time. As of today, this record has never been broken by anyone, although attempts have been made repeatedly.It is also important to remember that when keeping poultry it is necessary to observe strict sanitary standards and feeding regime, to give high-quality food to exclude any anomalies and pathologies: both in pets and eggs produced by them.
