Hard to tell from the pictures, but the back half is a shed. The access to the nesting boxes is inside the shed; here in the Pacific Northwest, it's nice to get out of the rain while collecting eggs and cleaning. The front of the coop opens completely for easy cleaning. We used branches from the woods for roosting bars, put curtains up in front of the nesting boxes (the girls wouldn't use them until we did), and made our own waterer from a free food grade bucket from Safeway and poultry nipples (incredibly easy). This is our own design, not terribly different from some others on here. My husband is an architect, so we had to have a home design.
