Two-yolk egg: features and causes of appearance

Probably every lover of chicken eggs sooner or later came across a two-yolk egg. Previously, they could only be found in domestic chickens, but now they are also sold in stores. Such eggs are tastier and more nutritious than ordinary ones, but the question arises, what is the reason for this phenomenon and is it possible to fearlessly eat two-yolk eggs?

How are they made?

Those who encounter such a miracle of nature for the first time are sincerely perplexed and try to find the reason. Many believe that there are chickens that carry two-yolk eggs, that is, it depends on the breed. But this is far from true. There are several reasons why chickens have eggs with two or more yolks, and not all of them are harmless.

• Very often two-yolk eggs are laid by old or sick hens. In addition to two yolks, there may be other deviations: a yolkless egg, an uneven curved shape, without a shell, with blood splashes. The appearance of such eggs in domestic chickens very often indicates that the bird has either a disease of the oviduct, or that the tone of the oviduct has already decreased due to age. Noticing in yourfarm such a bird, it is most often sent to the soup.
• Improper feeding of a young bird, which causes her hormonal imbalance. Also, such a disease can be at the genetic level, and not only because of the conditions of detention.
• If double yolk eggs are not laid consistently, it may be because two eggs just happen to be together in the oviduct.
• In addition, poultry farmers have recently noticed another reason for the appearance of eggs with two yolks in the clutch. If a bird has been fed hormones for a long time or has some kind of disease due to which such an anomaly is obtained, then it is likely that it will inherit this ability. That is why they try not to get offspring from such chickens.

What to do?

In fact, there are several ways to solve such a problem with poultry.

• The first thing to do is to replace all adult chickens with younger ones.
• If the problem persists, then review the diet. You may be feeding foods that are too high in hormones.
• Another reason why two-yolk eggs may be too long daylight hours. Reduce it first to 12 hours, and then gradually bring it up to 13-15 hours.
• If this does not help, then you need to contact the veterinarian to examine the bird for the presence of diseases of the oviducts.

Will there be chickens?

People who are far from agriculture, quite naturally, the question has arisen of whether it is true or not that a two-yolk chicken egg will bring twin chickens. Unfortunately, it is not. Such eggs do not bring offspring, as they are not suitable for the development of the embryo. Nature, as it were, rejects biological material from a weak or sick individual.

In a two-yolk egg, naturally, one of the embryos dies and, decomposing, poisons the second one.

Pros and cons of two yolks

The appearance of such an egg is no different from the usual. It is of the usual color and shape, but much larger in size. The weight of a two-yolk egg usually ranges from 110 to 120 grams, while that of a single-yolk egg rarely exceeds 70 grams. It should immediately be noted that the large size of the egg does not necessarily indicate that it contains two yolks. Regular eggs can also be quite large.

It should be said right away that you can eat a two-yolk egg. Only eggs that have some additional mutations can cause harm. A sign that should alert you when you break an egg is the presence of many blood streaks or clots there. Unfortunately, this suggests that the bird that laid this egg was sick. Eggs from a he althy bird will not cause any harm to your body.

Production of eggs with two yolks

So far, we have been talking mainly about domestic chickens. But many have already noticed that two-yolk eggs also began to appear in stores. What's this? Developmentsbreeders or some particular breed of chicken?

Unfortunately, we hasten to upset you. Poultry farms that produce a special line of eggs with two yolks simply feed their birds with hormonal preparations, specifically trying to get two-yolk products from them.

The end consumer has not yet understood the full danger of such eggs, and special studies on this product have not yet been carried out, since two-yolk eggs appeared on the shelves relatively recently. Previously, eggs with two yolks were sent for processing to obtain egg powder. Now they are “thrown out” for sale, and they cost significantly more than usual. It turns out that we are being poisoned for our own money, since it is not known how such a hormonal egg will affect our bodies.

Based on the foregoing, we can conclude that eating store-bought eggs with two yolks is undesirable, since any interference with natural natural development never goes unnoticed, and it is not known who will have to pay for it - us or our descendants.

How to tell?

Can you tell a two-yolk egg from a normal one? There is a special device - an ovoscope, which can determine the quality of an egg by shining it with special rays.

It is clear that no one will go to the store with such a device, although it is quite compact. Therefore, only visual differences remain. As mentioned above, such an egg is almost twice as large as usual, has an oblong shape. Colorshell corresponds to the characteristic for this breed of chickens. In addition, in stores, such eggs are usually much more expensive than simple single-yolk ones. Some manufacturers even indicate on the packaging that they are two-yolk.

Signs

And finally, a few signs associated with such an anomaly.

• It is believed that if an unmarried girl finds such an egg, she will soon get married.
• If a married woman gets a two-yolk egg, then we can expect an addition to the family, perhaps even twins.
• A man who finds such an egg is waiting for an increase in his male power.

Folk wisdom says that those who are lucky enough to find a two-yolk egg will soon gain fortune and fame, increase their well-being and bring happiness to their home. Our ancestors, having found such an egg, boiled it and cut it according to the number of family members, so that well-being would not bypass anyone.

And, by the way, scientists also did not bypass this phenomenon. They drew attention to the fact that before the increase in seismic activity in the region, many chickens begin to lay two-yolk eggs. So do not rush to immediately send your hen to the soup - take a closer look at her, perhaps she wants to warn you of an impending earthquake.

Conclusion

So, now you know that there is no "magic" breed of chickens that can lay two-yolk eggs. And supposedly the benefits of such eggs, which they talk about advertising -Another clever move by marketers. It is up to you to decide whether to eat commercially produced double-yolk eggs.

As for domestic chickens, we repeat that the presence of only two yolks in an egg does not cause any harm to the body. Again, the default here is that you don't feed your bird hormones. But in any case, this feature of your chickens should make you wary and reconsider your methods of raising poultry. If you are sure that you are doing everything right, and the veterinarian did not find any deviations, then most likely this is a mutation at the gene level, to which all living things are subject.
