Hi, I have 10 hens, 5 older hens and 5 new hens in pens next to each other. One of the original hens has lost all her feathers around her rear end and the other 4 are pecking at her and making it bleed quite badly. I cleaned it up and put her back but they were right behind her following her everywhere and pecking until it started bleeding again. Yesterday I put the 5 new ones in with the older ones and put her in the other pen on her on to give her rear end time to heal, but she looks really miserable and I haven't seen her eat anything either (not that I am with her constantly)! Have I done the right thing??
