Help someone!! I have two hens out in my coop, both with average sized single combs. The windchill is supposed to get down to -20ish. Their coop is warmer without much of a draft at all, if any, but their combs are looking a little pale and maybe discolored at the tips. I know you're not really supposed to take them inside, but I'm REALLY concerned. It's FREEZING out there. Any thoughts??? Please!! I could bring them back out in a couple days when it warms back up so it wouldn't be such a cold shock.
