The Little Giant Single Open Nesting Box is made of durable high density polyethylene that will not rust rot or corrode, offering an affordable alternative to metal nests. The smooth plastic surface is easy to clean and warmer than metal or wood. Its open back and top provide better ventilation and easier egg access, while the front edge helps keep bedding in place and the sloped floor allows drainage. It mounts to a wall or sits on a shelf and measures 17 inches long by 11.6 inches wide by 11.9 inches high. Available in black.
