We had a night and day where it dropped to -30, and rose to -18 the next day. The girls wouldnt come out so I moved the water into the coop... Bad idea. All 5 got some frostbite on their combs and or wattles. I brought them into a heated area until they heal and temp improves. But these two girls I am worried about. Brandy has a flat wattle and the black goes down in the crevices, and I cant get the neosporin down there with out massaging. Cinderella has sores, discoloration and blackening, swollen and she has been very lathargic today. I am very worried about her. What do I need to do?
