This is the roost in my coop, with a poop board underneath it, so you can see a different configuration. It has sweet PDZ on it, which really takes care of the ammonia smell. I have pine shavings on the floor, about 4-6" deep.
I clean the poop off the board every day. If the chickens poop on the floor, the shavings absorb the moisture and the poop dries out. There is no smell, unless someone has just dropped a cecal poop. The poop bucket smells in warm weather, but except when I'm scooping, it's covered and out in the run. I dump it into the compost bin when it's full.
Others have said to get the hardware cloth off the floor, but I'll say it too. It will be hard on your birds' feet, they'll scratch down to it and possibly get a toe or foot caught in it, and it's a rough landing surface when they jump off the roost. A cut on a foot is a recipe for bumblefoot, and you want to get rid of anything that might cause that.
