I like your roosts too. I took a couple tree branches and they go across the back of my coop, I thought they might be too close together, but they don't see to have a problem with them and aren't pooping on each other so I'm not going to mess with them right now, but I feel like they might be too high. This pic is from before I lowered the board. It's now flat to where the front edge is. I'm not sure how far off the ground it is, but the top of the back wall is 6' from the floor, so maybe 3' from the floor. As you can see, some lazy butts sleep on the edge of the nesting boxes. I've seen them jump from the box on the bottom right to the roosting bars, so I don't know if it's b/c they can't jump up that high, or if it's just b/c the box is there now & they're using it. My one chicken Jaiden has always had jumping issues so I'm not surprised she's a nest rooster. (The box contains my cockerel. He's slightly aggessive so I don't let him out w/ the general population (our safety, not theirs - he's good w/ the ladies) but he does have his own run. He's just has a very small inside space.)I also have linoleum on my poop boards but I don't put anything on them. I just go in and scrape off the poop. You can see our setup here http://onemountainacres.weebly.com/adventures-with-chickens you have to scroll about 3/4 of the way down to see our poop boards and coop setup. We added a ramp to the lower of the two roosts after the pictures were taken. Anyone that wants on the higher roost usually walls up to the lower and jumps over to the higher.
