For me here in the Steamy Southeast of the USA I have to have a coop designed to cope with heat and rain -- even hurricanes -- but my idea of a cold winter is a few days that don't break freezing. For someone in the northeastern USA they need to prepare for snow load on the coop roof blocking their ridge vent and days that won't break 0F.
