Coop is based on the Open Coop idea of as much fresh air as possible. It provides NO predator protection. So, it is basically a 3 sided room, with windows around the top in the 3 sides. Windows have covers to cut down on drafts in the winter. Coop is 6' x 6' x 8'. Storage is provided in the cabinet under the two 6 foot roosts. A removable poop tray slides onto the top of the cabinet and protrudes 2 inches to cut down on poop on the cabinet doors. Nesting boxes are removable for cleaning. Two boxes to start, additional boxes can be added above and across from those.
