Unless you're in a very cold climate, what you need is a large outside area for them to run in. All a chicken house needs to be is a place for them to roost at night and lay eggs. Not saying a good coop is not important, but I see far too many people building a nice and pretty chicken house, and then having only a few square feet for them to be outside in.
Having said that, you do have a very nice looking coop there. Nice job.
