Yes I use big cafeteria trays in one coop and those "plastic boots trays from TSC in the other// Take out the whole tray scrape it in a pile in the edge of woods After I sled them down the hill...exercise in walking the distance LOL) then use either a toilet bowl brush on the "treaded' boot trays. Or one of those soft $1 sponge dish mops on the big fiberglass cafeteria trays. Dry them in sun for a short while then back in the roost holder.. ESY Peasy..Oh if too cold then shake and dry with a paper towel and put back.. Now couldn't find my big cafeteria trays used so bought 6 pack on prob Ebay or Amazon. expensive but very durable for the long run..... Have big baking sheets on roost first. then the black cafeteria trays.
