Hi fellow chicken lovers-- I'm a newbie here & to the world of chickens. My DH and I are in the process of building a coop for our 4 chickens. Don't plan to have more than 6 chickens at most. Our thougts for size is a 4x4 house (photo below) with a 7x12' run attached to it. Do we need to raise house off the ground, as most of them seem to be? The house is actually a cedar wood playhouse we got from Sam's for a steal. We will staple chicken wire over all window openings, probably have wooden boards in the winter to make it warmer for them. DH wants to put a ramp up going to one of the windows, but if we do that, the chickens will not be flush w the floor when they enter, so another ramp inside? or should we make their entrance flush w floor? ramp would be up to the window on this side..... We are in NC and have fairly mild winters. Does this little house look like it will be enough to keep them warm? Thanks for your thoughts!
