One of our 20 week old pullets flew out of the run and was attacked by a predator. We believe it was a hawk. We couldn’t find her for awhile but she eventually flew back into the run. She had a wound on her back between her wings. We put an ointment on it and put her back in with the rest of the girls (9 of them). The next morning the would was worse and she had a much bigger wound down by her tail feathers. She was being pecked by the other girls. We put her in dog crate to separate her from the others but left her in the coop. The wounds are improving but still open. She still has large area with no feathers. When can I let her back in with the rest of the flock? Is this typical flock behavior?
