I have since doubled this, but layout is the same. Coop is 4x8, raised. I have a cleanout door on both sides. roughly 4" of pine shavings throughout. I want to try a poop board under the roosts on both sides to preserve the bottom shavings. I dont know if I should place them on the ground under them or place them just underneath them? I have not seen anything like mine with poop boards.
