I have one hen, Big Red, that is being attacked by my other 6 chickens (3 hens and 3 roosters.) It's gotten so bad that a few weeks ago I had to move her to the back of the barn by herself. It's like they're trying to to kill her! I've had her and 4 of the other chickens for a couple of years and 2 of the young ones (both roosters) were hatched last summer. Every time I try to reintroduce her to the flock, they start attacking her and pecking at her. She just puts her head down and takes it. Does she have something wrong with her that the other chickens detect that I can't see? Will I ever be able to move her back with the other chickens? I feel sorry for her all by herself.
