This is my pride and joy! I built this contraption BY MYSELF! Built it outside and my sister helped me get the darn thing into the coop...what a day THAT was! The poop tray is filled with sweet PDZ granular and I can only say if you haven't converted over to this system you're crazy! Best thing I ever did. I just take the kitty litter scooper (up there on the far left) pick up the poops from the previous night...takes all of 3-4 minutes...done! My roost bar is removable using some metal hanger thingies. My BIL sanded and routed the edges so it's real smooth on the girl's feet.
