I have a wood floor, inside my barn, converted to the coop, you can paint the floor, so it's easier to clean, mine is covered with pin shavings, which I just add new over, removing any really nasty stuff as I go....I live in a high desert area, and it works great here...are you trying to collect the poop? How high are your boxes and roosts? The roosts should be higher than the boxes. I recently moved my boxes lower, the pullets were sleeping and pooping in them, now they are primarily snuggled in the shavings, or on the roosts.
