i've just noticed i've got an injured chicken, i first noticed because she was sitting down and had laid a half formed egg, when i picked her up i noticed she has a wound on her back, down to the bone but not too big, about the size of the end of my finger, it looks like a puncture wound, it had some feathers stuck in it so i've pulled them away and the wound looks clean and not too major
what do i do?
what do i do?
