OK new chicken owner here and I could use some help. My five pullets are four months old they've gotten along great up until today. This morning I noticed that one of them had some damage to her comb. I'm not sure if it was done by one of the others overnight but the blood was dried so I cleaned it up and put some wound spray on it but the others were still attracted to it and pecking at her head. So then I put this cover-up stuff on it (see the photo) They are still pecking at her head. I have her separated right now and I'm wondering if I should keep her separated until the wound has more time to heal? I love all my girls but I have to say it's horrible to see how mean they can be. Thank you so much for your help I would appreciate any and all advice!
