I use two washing machine drain trays the same way with PDZ on them. 5 minute clean up with a cat litter scoop. Easy peasy.I use a piece of smooth cheap plastic floor runner under my roost at nite as a poop tray. Just slide it out in the morning, wash it off and slide it back in a nite. Poop slides right off and half a bucket of water cleans it, quick and easy. In the winter when it's below freezing the poop freezes on it and just pops right off, I don't even have to wash as often. Not sure if that might work for your situation but it's an inexpensive option and can be cut to fit into most spaces.
