How to stop frostbite in japanese bantams?

[Anime2lover]

I have a adolescent bantam too that I think is a Japanese. The weather is freezing out just about every night and I have started noticing that his comb is getting frostbitten. I put him in with chicks that are a little bigger then him and have access to a heat lamp but that doesn't seem to be stopping the frost bite on his comb. Other then bringing him alone inside the house, what else can I do for him?? There is no breeze getting in where he is, it is thoroughly weather proofed and has a loft that prevents direct wind from our ventilation window while still having enough ventilation. It is not severe yet and I don't know for sure if it will get that way, and I don't want it to. He is the only one being affected by the cold, the chicks are handling it just fine due to the heat lamp and being fully feathered. They aren't getting frostbite, and neither are my silkies which are younger them him and are also being kept in.

No location in your profile, so hard to determine the extent of COLD in your area. If all the other chickens are fine, and you state that you are also providing a heat source, that is a very puzzling situation. All I can suggest, is let the frostbite take its course. The comb will heal without your intervention, and tips will fall off. I know it is sad to see harm happening to your chickens
I have a Japanese Bantam, but is a hen. Not a very large comb.

Cold doesn’t cause frostbite; moisture does. There shouldn’t be anything blocking the ventilation window.

We are in Rhode island so it doesn't typically get freezing freezing like the arctic. We do get freezing winter weather though. He is a
easy loosing one of the tips, possibly two.
