I only have two girls old enough to lay. As the temps got hot this Summer I noticed my egg production was cut in half?? Turns out Chick(brown) stopped laying and I could tell it was her because her red head thing(technical term) turned a light pink. Apparently it is a hormone thing?? She laid great all winter so I’m excited for her to return to laying when the heat drops down. It’s good to know I have at least one good Summer layer. Can you see the difference in the picture?
