I've built a version of the Purina coop with a raised floor made of 3/4" treated plywood (4' x 4'). For a coop of this size, with this type of floor, what would you recommend for poop maintenance (methods and materials)? My girls are moving in very soon! Expected flock size will be three to start and probably never more than six. I'm in a hot climate that doesn't freeze very often (southeast Texas). Thanks for all ideas in advance
