Thanks, Walt!
How far are your roosts from the wall? It almost seems like when I put them up there they feel crowded because the one day I had Omelet (our alpha chicken) facing forward, they all hopped down but the day I had her facing the wall she would not turn around and so would not hop down and so they all stayed up there.
I'm going to post a picture of the wall opposite the window next. The window is framed with 2x4s so attaching a roost on that side is no problem, but the opposite wall is about a 5 foot stretch of the 1" shiplap boards and I can bow it ever so slightly if I push on it. I'm going to need to figure a way to attach the roost to that side if I move it... Do I just put up another 2x4 post from the floor to the ceiling?
I just made a thing like they use for jumping horses. It is free standing so it is moveable if you look at it from the side it looks like an "L". There are 2x4's standing upright and 2x2's at 2' and on top at 4.5'. When I go in at night for headcount some are facing the back wall some facing me. It is about 2' from the back wall. I;m messing with their heads today I switched their nests around. Yesterday I went out and there were 4 eggs in the same nest the other has not been used since I put in fresh hay, so I switched them, I want to see if they lay in the same location. They do seem to crowd to the northern end of the roost and lay in the northern most nest. Trust me they will figure it out. This morning they all were still up top "sleeping in", most days some at least are on the floor. I have 3 beehives (1st year). 4 pygmy goats, 8 layers, 25 CX meat birds, not to mention the cat, 2 dogs(small), and 2 parrots I have learned that my "critters" know better than I do, what they need, and if you pay attention they will tell you.

PS afterthought... you could cut a 1x2,3,or4 whatever or a scrap 2x4 cut a notch in it the size of your perch and screw it to the inside wall. That would be like a closet pole, you would have to cut the perch exact length +-1/4".
