How are double-yolked eggs formed? In fully developed, healthy hens, this production process is well coordinated - one yolk is produced each day, producing a normal egg. However, in hens that have just started laying eggs, the parts are not yet working together well enough, and "abnormalities" can occur. For example, after producing a yolk, the "control center" does not receive the signal and produces another yolk. Two yolks into the fallopian tube, although increased the burden of the subsequent departments, but these departments a little extra work, but still able to work normally. So these two yolks are similarly wrapped and molded in egg white and expelled from the body - a double yolked egg, thus produced.

The "egg production process" of a hen is regulated by hormones. Abnormal hormone production can produce double-yolked eggs.

Since the production of double-yolked eggs is due to hormone abnormalities, is it possible to use hormones to make hens produce double-yolked eggs? Although double-yolked eggs may be produced naturally by hens, could there be "hormone eggs" in the market?

Theoretically, such a possibility cannot be ruled out, but in reality the likelihood is negligible.

"Illegal traders" have to do illegal business, always in order to "profit", and "with hormones to produce double-yolked eggs" can bring them illegal profits? On the one hand, double-yolked eggs are not much more expensive than ordinary eggs, and they are sold as "big" eggs. Although there are some places where double-yolked eggs are used as a symbol of good luck, you can't tell before you break them, so you can't rely on the "double-yolked" eggs to fetch a high price. On the other hand, the use of hormones in chicken rearing is currently banned in countries all over the world, so there is no research and no commercial production. Even if such a hormone exists, it must be "highly efficient and low-priced". The use of such hormones to produce double-yolked eggs is probably akin to "hitting a mosquito with a cannon," and is more likely to result in a loss of money than a profit.

In fact, even if someone did use hormones to "promote" double-yolked eggs, the hormones affect the hen - the hormones serve as a signal to lull the hen into producing an extra yolk. But that doesn't mean the hormones get into the egg.

Based on an analysis of the composition of double-yolked and single-yolked eggs, there are no noteworthy differences between the two. Whatever is in a double-yolked egg is also in a single-yolked egg, and whatever is in a single-yolked egg is not bad in a double-yolked egg. While the proportions of certain ingredients are slightly different, the difference isn't that big - at least for nutritional purposes, that difference is completely negligible.
