My hen has been attacked, and her feathers are gone from a place on her side, and there is a wound with the meat showing. Not all the way to the bone, and may be able to survive it. The wound is about the size of a 3' x 3" area where there has been some skin pulled away. How can I treat it and help her to survive. She is walking around, not bleeding just a gaping wound and no feathers there. I have her in a cage now, don't know what attacked her but it got my rooster who was trying to protect her. Is there something I should put on it or try to bandage it or what can I do for her? Or what can I give her to keep from it getting infected?
