My barred rock hen Bebe got beat up on by the other girls when we had a really nasty cold snap. They ripped out a lot of feathers on her back and kept her from coming into the coop. I brought her in the house and have been giving her food and water (with apple cider vinegar in it), but she's not really interested in eating or drinking. I've cleaned up her back and made sure there weren't any puncture wounds. She's not wheezing or anything like that. She's just sleeping all the time. I'm concerned that she'll get dehydrated and weak from not eating. What can I do?
