One of my Hens I will be honest I am not sure what she is the only one out of my group I have never been able to identify. Anyway She has been hanging out in the coupe more and more so this morning when I went to let everyone out, she was staying in still, I picked her up and she has a bare area on her backside, and I lifted up her wing and she has a rip the size of a small egg. It looks as if it is trying to heal over, but has to be hurting her. I am thinking the New Rooster might be doing this to her? Which might explain why she has been hanging out in there the last 2 days. She appears fine otherwise, she is eating and drinking but I am concerned! I took her today and placed her in a small cage by herself. I put some Antibiotics in her water to help her heal. I had to get to work, so I am going to clean her up very good tonight and see what we have going on. What should I treat it with? What else should I do? Should I keep her isolated? Will they hurt her if I keep her there a few days or weeks to let her heal? When I go to put her back in with her flock will they be mad because she has been isolated? What to do???
