i saw some articles about frost bite on combs and wattles and that dog dishes were bad for that.. so i watched my roos drinking out of a heated waterer and they get their wattles wet anyways.. we have below freezing temps for quite a bit of time in the winter and tons of snow.. what should i do to prevent them from getting frost bite. the coop is insulated. the water heated. but they will be going out when we snow blow the run. and after seeing water dripping off them i am afraid they will get frostbite on them
