Not an expert, but I do recall reading that chickens were designed to eat bugs, not grain.

Of all the grain I know to avoid, corn is at the top of the list (way too much omega 6). (Wheat is not your friend either, but that's for a different thread.)

As I can, I also avoid GMO Frankenstein foods, including modified grains.

Might the hens have been fed GMO garbage, and could that affect their endocrine systems?

This is the same protocol my wife follows. The ladies are still laying.

You are mostly wrong.

Chickens eat bugs yes and can even live on them but need grain if they are going to lay eggs.
