When doing health checks on our chicks this morning I found one of our week old Sebright/Silkie babies has a beak injury. I do not know how it happened, there has been no issues with aggression between the 5 chicks in the brooder. The chick is drinking from the poultry nipple and appears to be eating. The chick is not bleeding, it does shy away from me touching its beak, I'm sure there is some amount of pain.. What can I do to help the little one heal? Will the beak regrow/heal? Do I need to treat the chick with any medications?
