I need a small coop design for about six chickens. Permanent structure. Would prefer about 2' off the ground with a way to get in and clean and collect eggs without it being too large. I don't need to enter it myself. I have a small place in town and need something that isn't too fancy. I plan to keep the chickens in this coop surrounded by a 10x10 or 10x20 run and possible free range during the day for short periods. Thanks!
