I have 8 hens. One of them is always getting picked on by everyone else. Every time I try to put her back in with them her neck is pecked so much it bleeds. I’m now keeping her in a separate area with one of the younger hens that was just introduced. She is let out to free range with everyone else and they ignore her then. We have three chicks that have not started to lay that have just been introduced. They are fine with her. We also have 4 other adult hens who pick on her. I can’t keep her separated forever. Help!
