I have a 4' by 8' coop for 8 chickens. 99% of the pooping inside happens from the perches/roosts. The droppings boards under the perches have proved invaluable since their install. I like to clean up about once a week inside the coop. I spread a thin layer of pine chips on the board where the droppings collect so when I go to empty them the poop slides right off. There are also chips on the vinyl floor in the coop but I am lucky where my chickens don't spend alot of time standing on the coop floor pooping, but more like a highway to the nesting boxes or to jump up to go roost. In the floor of the coop you will see very few poops where they are easy to clean up off of a thin layer of shavings, This system keeps the floor very clean and you don't use chips to cover up the poop because its all gone when you clean.
