How does a hen lay an egg and what causes the formation of a double yolk egg?

The hens have an ovary and an oviduct. The ovary is responsible for the development of the egg. A hen will lay an egg every day which is as long as it takes for the egg to form fully in her reproductive tract.

The egg formation starts in the ovary which then transfers into the oviduct.

The egg travels further along the oviduct, where the yolk gets enclosed in egg white, followed by the inner and outer shell. The egg leaves the oviduct and enters the uterus, where the outermost hard shell forms. The fully-formed egg then exits through the vagina and out from the cloaca.  

Sometimes, two egg yolks are released together causing them to be enveloped in one shell. The yolk formation starts soon after the egg is laid by the hen. In some instances, the hen’s reproductive system produces the egg yolk too due to a hormonal change or overstimulated ovaries. 

 Consequently, the new yolk becomes a part of the previous egg, hence you find two yolks in the same egg. 

The condition is prevalent among hens, who have just started to lay eggs or at the end of their egg-laying days. However, there are other deep-rooted factors that can cause such a phenomenon such as hereditary factors and breeds.

There is also an environmental factor that contributes to double yolk egg production. The daylight plays a crucial role in determining the egg-laying cycle in eggs. 

As the length of daylight increases as summer nears, the reproductive system of the egg gets manipulated by the change in the period of light. Hence, this phenomenon is exploited by egg producers, and the hens are raised indoors in controlled lightning. 

However, as the hen adapts to its new environment, the ovulation cycle reverts back to normal.
