OK..... this summer I installed poop trays, and started using PDZ for my chickens. I love it. I also love the extra floor space the poop trays give me. Can I do something similar with ducks? My ducks are happy to go up a wide shallow pitch ramp. Could I set up a second story in the duck house with a ramp up to the second level? Anyone try anything like that? Anyone try using the PDZ with ducks? I am not exactly sure how it would work, or if they would track it all out in just a week since they would be sitting in it, instead of sitting on a perch over it. But, maybe since Muscovy perch, I could actually put a perch over the poop tray, just like with the chickens? Anyone have any experience with any of this?
