Did he quiet down? If he did, I'd give him time to heal and give the others time to forget and try again. Be sure they have enough space and enough protein.
okay well the chick wouldnt stop cheeping so i put him back with the others and i figured if they really targeted him they would have probably killed the chick by now. I dont know if im really off base by doing this or not and the chick doesnt look any worse.
