Our chickens had outgrown their makeshift roost and needed something bigger, but since we were in the process of moving I did not want to build something we couldn't take with us. Also, I wanted something that would catch all the poo and be easy to clean. Here is what we came up with: The top roost is about 4 feet from the ground, and each level has a heavy duty tray to catch the poo. The trays are 2ft X 3ft and we got them at Lowes in the concrete mixing section for about $13.00 The rest was made from scrap wood I already had in the garage leftover from other projects. Each tray slides out for easy cleaning, and I put in a couple of inches of stall-dri so that any poo that falls in there gets dried up and doesn't smell. Plus, when it's time to clean, I just use a litter box sifting scoop and scoop out all of the poo, leaving behind just the clean stall-dri (this also keeps the poo from sticking to the inside of the tray). As you can see, my chickens LOVE their new roost, and I plan on making more of these when we get moved into the new house and build new coops for them.
