I'll be working on my roosting area within the next couple of weeks. I like the idea of having the "poop tray" up off of the ground. Easier to get to and clean. I plan on using the wet vac to clean it. We can only have 4 hens and contemplating one bar or two. I want to keep the noise down as much as possible, so am leaning towards one bar to reduce pecking order squabbles.
The one on the right comes out, away from the wall, at an angle (we needed a longer perch). You can see the little piles of poop; proof that they work.
