Hello, BYC. So this is my first year raising chickens...they have been such a blast! Our coop is an old shed that we renovated and then added a large connected run to it. We have 12 standards (Buffs, Barred Rocks, New Hampshires, Sex Links, Sussex & Americaunas) & 5 Bantams (Sebrights & Duckwings). The shed/coop has been great during the summer, but now that fall is staring to come on I'm starting to think about winterizing. I'm wondering if it will be a problem that the flooring is cement? I live in far Northern Colorado. The climate is very dry, windy and quite cold in the winters (well below freezing, though rarely for an extended period of time). Also, the coop has one larger South facing window, but I'm considering adding another Eastern facing window to get the early morning sun in there for my ladies. Any input/information would be very much appreciated!
