I am in the process of building myself a coop. I am shooting for a relatively small footprint, and something that can accommodate up to four chickens. My debate is whether or not I should build a run. Let me explain... The coop is about 4' x 3' and stands about 2' off the ground on four posts. My original plan was to attach a run to the side. The chickens will have an enclosed area to run around in. The ground is sloped and I worry that adding a run will make it difficult to set the house down without it being slanted. I also am not sure if there is any advantage to having an enclosed run, as it probably wouldn't be predator proof anyway and I'll probably have to close up the coop every night anyway. I had originally envision the chickens being able to sort of let themselves out in the morning, but I don't know if that is safe, and I want it to be mobile, so cement and the like is out of the question. I live in a very suburban area, but there is a large forest park near my home that houses raccoons, coyotes and the like. So I'm asking for your experience. Is it worth building a run?
