HI, I have 15 chickens (13 golden comet hens, two roos) who are 8 months old. Due to family emergencies curtailing the building of a weatherproof winter coop, they are in a not-very-warm house with attached run, and I use tarps wrapped around to keep drafts away. Not ideal but the best I can do for now, and they seem to be doing ok. My question is, should I be giving them any different kind of feed to help them deal with the single-digit cold we've been having? I understand they don't put on fat under the skin to help insulate like other critters do, but they've got to be using a lot of energy to keep warm, anyway. They get layer crumble, and I give oatmeal (raw) twice a day, and sunflower seeds. Also some cracked corn, but I've read that they shouldn't get too much of that. What's best for a winter diet? I give leafy greens and yogurt, too, a few times a week, and occasional treats like carrots or apples. Is this ok, or should I be doing something different? The girls are still laying, 8 - 10 eggs a day!
