I think it's mainly the roosters you have to worry about that have more pronounced combs and wattles. I have a great chicken book that list characteristic of chickens when trying to pick the right breed for yourself. One sect is about breeds that are prone to frostbitten combs. Here's what is listed:
Andalusian, Campine, Dorking, Leghorn, NH Red, NH white, Rhode Island Red (Roosters are more likely than hens to suffer frostbite; their combs are larger and they don't tuck their heads under their wings while sleeping as hens do.)
I hope this helps.
