Try sand. I read that a lot of people are happy with sand in the brooder as bedding, so I decided to try it. My chicks are 4 days old and the amount of poop has really gone up. I have paper towels on top of sand, because they were eating the sand in the early days, but now I'm starting to transition them off the paper towels. The sand seems to be working better, because the poop sort of gets buried in the sand as they walk and push it down with their feet. So there's less accumulating on the surface. I got a reptile poop scoop (smaller holes, so the small poops don't fall through) and it's really easy to scoop. Their feet are clean. There's less mess overall and it's easier and faster to clean. And less wasteful. Paper towels are hard to find these days so I don't want to waste them on chickens.
