17 degrees below zero this morning. Had the heat lamp going which kept the coop at a balmy 1 degree. Looks like the red star has a bit of frostbite on her comb. Not a bad case, just the very tips, maybe 3-4mm. She has a freakishly big comb, so no surprise that it was her. Well, she'll be getting a little Bag Balm on there this afternoon when we bust out the oppressive heat and top out in the teens.
