So while I was reading up on the forums designs for coops that can handle very cold winters and such, I came across JackE thread on his fresh air coop. I really love that coop design and from what I was reading there hasn't been an issue during winter, But a few things I kinda have wondered about these designs, because from the books i saw most of them are big coops. His happened to be 8'x16' if I recall and he had 11 chickens. I will not have more than 8 chickens more likely 6 to be honest, and I don't have a lot of land now yards not that small but not huge and I still want room for running. Can these designs be built say like 6'x8' and hold up to 8 chickens, "I'm using 8 being high point but most likely 6 just trying to over comp" safely and comfy? They will be free ranging the yard as often as possible. My other concern was and not sure if JackE or others with this design can put info, what temps can I expect during winters 8 deg to 12 deg days to be inside these coops? and if you have to cover the windows at all during the winters or have any form of heat sources inside? From what I can gather these are suppose to be solid designs though.
