I am having a 10x12 shed converted into a coop. The first four feet will be for storage with a wire wall dividing the coop space from the storage space. This makes my chicken area 8x10. Where should the pop door be located? The run will be L-shaped, covering the left and back side of the coop. Should the pop door be in the middle of a wall or on a corner? I am thinking I should put the roost along the back 10 ft wall. There is a window on both sides of the coop, would the roost be better running in front of one of the windows? Can you believe trying to figure this out is keeping me up at night??
