My chickens always go in the coop at night…except one rooster about 2 weeks ago when the temps were in the single digits for some reason didn’t…. I found him on the fence the next morning. He now has significant frost bite on his comb. So far he’s walking fine and toes look good. He’s been his normal self, eating and drinking, then today he started turning his neck a little to one side and kinda shaking his head a little, not too much but somethings definitely up. Advice on what’s wrong and how to treat?!
