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.
