Frostbite Rooster comb

Just leave him outside.
He'll do much better staying with his flock.
What is the ventilation like in your coop?
How large was his comb?
I'm further north than you and I'm going through the same type of weather.
When we went -19F, my senior rooster got frostbite on the back of his comb and his already frostbite rounded tips. When it gets THAT cold, birds with larger combs are vulnerable. There really isn't anything reasonable you can do to prevent it. It will heal. The dead tissue will fall off.

This was him in the spring. He is young it's his first winter.

Yeah, is one reason I got Dominiques with the rose combs instead of Barred Rocks with big single combs. I kept a cockerel out of the batch and gave one to a friend. Happy to say both are darling boys, respectful to humans and kind to their hens. The pullets are equally sweet in the flock.

I definitely prefer the rose combs.
All the hens are fine he is the only one with an issue.
