You can easily clean up your chicken coop if you just use sand as a litter material (instead of wood shavings, which absorb and hold moisture) and create a long-handled kitty litter scooper as your cleaning tool.
Why re-invent the wheel? If it works for a cat box, it’ll work for a chicken roosting area.
