When I raised chickens in Montana that was one of the fall rituals was making sure their combs were trimmed to prevent frost bite and make it easier for them to keep warm. The comb loses an incredible amount of heat in the wintertime. Look at the ring neck pheasant or any other cold weather surviving fowl. No combs to speak of on any of them. Remember, all domesticated chickens were bred and developed from Jungle Fowl where the comb was critical to help cool off the bird. Not keep it warm.
