I have a hen who is about 5 years old that was attacked by a coyote and injured. It looks like it tried to grab her on her back it got a mouth full of feathers and ripped off a piece of skin about the size of a 50 cent piece in the middle of the back between her wings. She is not bleeding heavily and I don't see any puncture women. Going to clean it and then put bag balm on it but I don't want her picking at it. Should I cover it and put a wrap on it or should I leave it open? Also does anyone have any idea about how long it would take a wound this size to heal completely? I have her inside and a small dog cage separated from everyone else. She is walking fine I did not see any other injuries
