How do you get a chicken to lay twin yolk egg?

Here's why:

* Natural Variation: The occurrence of double-yolk eggs is a natural phenomenon. It happens when two yolks are released from the ovary simultaneously and are enclosed in a single shell.

* Genetics: A chicken's genetic makeup influences the likelihood of laying double yolks. Some breeds are known to be more prone to them than others.

* Age: Young chickens and older hens are more likely to lay double yolks.

* Nutrition: A hen's diet can play a role. A diet rich in protein and calcium can encourage multiple yolk production, but it can't be guaranteed.

In summary: While you can't force a chicken to lay twin yolk eggs, you can increase the odds by choosing breeds known for them, considering their age, and providing a balanced diet. However, it's entirely up to the chicken's natural processes.
