If you mean the "hen-house" when you say"coop area", yes. I went with it being 5'-4" square to allow for more sf/hen than the original WCC design. The short 2x4's still need to go under the floor at the perimeter at front/back like I have installed on the side. The other larger opening on the front next to the hen-house portion is the opening for the dutch-door.
Yes, I meant the 'hen-house'
Sure your hens will like it. Double door should really facilitate keeping it clean. Is the house a bit higher off the ground? Going to be fun getting beneath there and cleaning out if it isn't.
