It worked fine for our 3 barred rock chickens! however they have free range outside of the coop and run during the day-otherwise I feel it's too limited a space for adult chickens. We put it together in a couple of hours, and painted it too so it would hold up to the elements in Montana. The chickens liked to roost on the little arm that sticks out to maneuver the sliding door open and closed, and it eventually broke from them sitting on it but I feel this coop was worth the reasonable price overall.
