Newborn 1 day old silky #12, who is 1-2 weeks younger than siblings, is terribly injured. Her head has been pecked. It appears there are pecked holes on top of her head, and her fur is gone up there, seems swollen and throbbing. She was with the 2 broody mamas being babied and cared for, while other 2 mamas tended to older 11. Somehow, in a few hours, she was injured. We are taking her inside to brooder, alone. What can we do, please?
