Poops clean easily with a cat poop scoop, and doing so every day makes for a really clean coop.
That's what I do as well. I keep a garbage can outside filled with pine shavings. I take an empty 2 gallon bucket into the coop and scoop out the bigger clumps and mats and dump it around my blueberry bushes. Then I fill the bucket with fresh shavings and dump it in the coop. I do a couple buckets a week and it looks really nice and smells good. I'll probably shovel everything out once or twice a year. I also got a giant litter box which I filled with sand for the girls to play in. They're slowly mixing it in with the shavings and I'm kind of liking the effect.
