Seramas?Wait so heat lamps cause humidity? I use a heat lamp, and switched to red bulb this year. I have had several chickens with minor frostbite on their combs, but I think it was from the steamy chicken bedding full of composting poop, IDK. I really need that lamp, because the little bantams are so sensitive to cold. Even today was only upper 30's or so, and they stayed inside for most of the day. Also, any good tips on keeping the cop warm? The roof is insulated but the walls are just wood, and the doors have these annoying cracks where cold air and drafts get in.
