I have a wooden poop board under my roosts and I got a piece of linoleum and cut it into sections so that I can lift it out in nice weather and hose down. I also sprinkle a good layer of shavings with DE mixed in and it is very easy to clean with a kitty litter scoop. I remove the solid and even if they have runny poop, once it gets covered with the shavings and the DE dries it out, it comes right up. I do not do any "scraping" I can see on my wooden ladder how the poop sticks to it and it is difficult to remove. I use the same litter from the floor for the poop board. Works great and in the spring I will wash all the linoleum pieces. It does not curl. I would imagine that it would depend on the material. I've gotten so many ideas from this forum that I hope this has helped someone
