I have a question about one of my hens. She is a Buff Orpington. She's around 7-8 months old. For the past several days she has been staying in the next box day and night. I do not have a rooster so the eggs are not fertile. The first day I got an egg from under her, the second day she was still there but no egg, yesterday she's still in the box and I found another egg under her. She tried to peck my hand yesterday when I removed the egg. Does this mean she is wanting to set on her eggs? Could she be sick?
