We have six chickens (I think they are pullets right now?). Depending on how we do with these, we will get more in the spring for a total of around 12 or so. Currently, our coup is attached to our house. The dimensions are 12' x 3' with a feeder box, 6' x 6" and a nesting box that is two layers, 6 on top and 6 on the bottom. We just decided to let our chickens free range. Is our coop to narrow? Will it work for them in the winter? We get quite a bit of snow.
