It is a small tear, and I washed the blood off of it, her face and feathers. I put ointment on it and put her back out in the coop on a roost for the night. Do I need to separate her from the others? There is no visible blood on her now but I'm sure the tear will turn dark as it heals and might be an attraction for pecking. The birds are not in a pen. There are 11 that run in a 24 X 56 foot open area.
