A week or so ago, we adopted 12 young chickens (2 roos, 10 hens) from a friend who had a lot of chickens and we suspect were overcrowded from their feather conditions (bare backs, some bare necks, no lice or mites). Well, one of my black sex links has hung out in a nesting box almost constantly and I thought maybe she was broody so when I go in, I try and get her out to drink and eat. (There's never eggs under her) Well, this morning I pushed her out of the nesting box and she joined the flock but I noticed as soon as she was around the other hens, she crouches down to the ground. As I watched, it's because they are mean to her and pecking her!! Should I isolate her in her own pen with food and water for a few days, put another hen with her, or let them be?? Thanks so much!
