One of my silkie chicks has a wound on her back just above her tail. I saw her pick a fight with a d’uccle hen today. Also when I went to check on them tonight momma and her chicks had stolen my silkie hens corner she like to sleep in. I convinced momma and the chicks to move so silkie could have her spot. That’s when I found the wound. I don’t know when it happened. It was a nice size red wound and I could tell they feathers were slick looking from blood. I did seem to get any on me when I looked at it but it was dark and all I had was a phone light. The chicks are six and a half weeks old. What do I need to do to help her? Do I need to pull them out of the coop? I’d just gotten them started with integrating as a family with out any barriers. What do I treat it with? Any help will be appreciated.
