I am also about to finish my coop with the same final touches. I plan to try a couple of different roosts to see which they prefer. One idea I had was to use a wooden closet rod and the other was make one out of 2x4's. Use two 2x4's for the sides and put 3 2x4's inbetween them at each a differnt height.
Some folks recommend the roosting places to be all at the same height to discourage pecking order problems as the head hen will always opt for the highest spot and the picked-on one will always be assigned the lowest (or..in chicken minds...I think....the most unsafe) place.
Gotta restate the importance of the poop board link: https://www.backyardchickens.com/t/...-graphic-gross-poop-pictures/430#post_9487122
What the poop board does, besides ease of cleaning where most of the poop lands, is that it captures more coop living space below. Perusing through the thread, you can see how some have utilized the space. (great for smaller coops)
-food and water under the poop board
-nesting boxes can go under there
-Someone on post #146 I think, put a brooder pen under there....or a place to put younger chickens before integration
