In the barn, there is a concrete floor. I scrape the stuff up daily. I'll be adding sand in there, when I have some more.
In some spaces, there is ceramic tile. That's easily cleaned too.
I clean all of my animal spaces daily, usually first thing in the morning. The smell, if any, is gone quickly. There are few flies. The easiest one/fastest one to clean is the sand. I can usually tell what the poop is (solid, runs, weird) even with the sand method. I could even tell there was a shell less egg.
I also put sand on wet stuff. It dries it up the poop quickly and the smell goes away fast. And I put sand in hard to reach places where poop ends up. The sand sucks up the moisture and I scrape it out of there and on to the sand floor of the coop. (I didn't design the coop. I just haven't gotten around to a full remodel yet, so that I don't have chickens pooping in hard to reach/hard to clean places.) The coop has a plywood floor. With the remodel, it will have the vinyl floor under the sand. I don't use a poop board. I clean the spaces daily (in the morning) and the animals are usually out all day until bedtime.
