I have found that my seramas have been quite hardy over the winters. When I have older birds I'll move them into the shed with a heat lamp, otherwise they stay in the big coop. This year I have had no problems at all even with the terrible cold and high winds, and I decided not to close off the front of the coop this year. They aren't in direct wind or weather, but it's not insulated like last year either. The front is just a panel from a dog kennel. They are healthy and active - doing their normal chicken thing during the day, and they snuggle together at night to sleep. Keep in mind that we did place our coop in such a way that the opening is as protected from the weather as possible.
