👉Double yolks are fairly uncommon, around one in one thousand eggs will be a double yolk. Triple yolks are exceedingly rare, but not unknown!

👉What happens is that a yolk is released and then another is released within a couple of hours. These two yolks get encased in one shell. Needless to say, this is a large egg which can cause problems like egg binding. 

👉You can get a double-yolk when the ovary is too 'enthusiastic'. The ovary produces one yolk, and instead of waiting for the normal period of one day, it quickly produces another yolk. The two yolks then move together through the rest of the process, and get laid as a single egg—with two yolks inside.

👉The issue can be hereditary, but it is most common in production pullets just coming into lay and occasionally older layers coming to the end of their cycle.

👉The younger pullets coming into lay are suffering from hormone change and imbalance which can cause the double yolk phenomenon. Once they have settled into their routine laying pattern, double yolks should disappear and be replaced by regular eggs.

👉They are considered ‘imperfections’ in the Egg Production Industry.

👉If you were wondering is it possible to hatch out a double yolk egg, the answer is usually not, although it has happened. If they do hatch, one chick usually succumbs since the amount of oxygen inside the shell is limited and the stronger chick will survive.

👉There are very rare instances of both chicks hatching.

👉Another way to prevent early double yolks from young hens is to “not push the issue.” Meaning, don’t do anything to rush them into laying eggs, like adding a ceramic egg, or overfeeding thinking you are promoting new egg production.
