For those of you in the cold climates, what do you do-if anything-to prevent frostbite on the roosters combs? We had about a week of chilly temps, like 20 at night. I went out the first evening and smeared chapstick on him, went to store for vaseline the next day and applied a thick coating it like every othe evening. Poor bugger still ended up with frostbit comb. Any suggestions other than heated coop? Thanks
