Got your birds yet? I put my roosts 15" from the walls. Observe them on the roosts, and see how much space there is between tail feathers and wall. Do I see a light socket hanging above that roost? If so, that's a danger. Birds try to eat EVERYTHING that they can reach, and with a socket above a roost, they very well may be jumping up to taste it if they can't quite reach it.
One of my girls decided she needed to launch herself off a perch to get a strip of fly paper I had hanging in the coop. I discovered her dilemma when I went to put the girls to bed, and saw this poor white hen, dashing madly around the yard, trying to outrun something blue that was following closely behind her. I finally caught up with her to find that the entire strip of fly paper was wound over her back, around her butt, under her wings, with the blue cardboard tube trailing behind her. we had to soak it off with baby oil, and cut most of it out of her feathers.
