The basic words coupe design would work in basically any conditions. But you have to build it specifically for your area and which way is the winds come from. As long as the chickens can stay out of the wind and stay dry they will be fine in your weather year-round.It doesn't get extremely cold here in Northern California (perhaps dipping into the 20's a few nights during winter, but we get some pretty decent winds and sometimes sideways rain. Would the Woods design still work in those conditions?
