I only have 3 birds, so...
My coop is similar to yours. I LOVE the slide out drawer. It's very shallow, shavings won't work (in mine, anyway). I put a thin layer of Sweet PDZ down (not even .5 ") and every day, I pull it out all the way, empty it into a long skinny (pre pasted wallpaper) tray. It's really too shallow to scoop. Then I put the drawer back, put a colander in (on the floor), empty the tray into the colander and shake it around the floor. Takes me less than 30 seconds. I do it every day--it couldn't be easier. No smell...ever They only use that part of the coop at night, they don't romp around in there during the day. We also used sand on the floor of the little attached run. It got too wet for our liking, a lot of moisture is bad in the cold. We built (w/2x4's and plywood) a "giant cookie sheet" caulked, painted and set it up on some bricks. Then we set the coop on top of that and filled it with 3" of sand. I clean that sand w/a kitty litter scoop. Perfect!
