The coop portion is 4' x 4' not including the exterior nest boxes. The large door on the front of the coop is great for when we need to reach all the way back into a corner to clean or catch an uncooperative chicken.
The window to the left will have a plexi-glass panel installed when the temps begin to drop.
The run portion of the coop is 4' x 15'. The coop is in our backyard which has 4' welded wire and two strands of electric wire all around.
The pop door assembly allows us to open and close the door without entering the run. We just let the door down in the evening after everyone has gone to roost.
