One of my Auracanas has a bloody spot on her back just before her tail feathers. Its about the size of a half-dollar.. All of them have lost a lot of feathers this winter. The roos are to blame. But this one really looks injured. She is active and doesn't seem to be concerned but I want to dress the wound. How to I get her to let me do it? I will be doing this alone. Any tips will be appreciated.
