I am in the process of trying to sketch out a design for our coop we want to build in a few weeks, and want to make sure I am getting the roosts and poop board placement correct. I am figuring for about 1 foot of roost space for each chicken, will probably have two roosts running parallel to each other. How far from the wall should the back one be, and how far apart should they be? I really don't want them pooping on each other! Should I make them the same height so there is no squabbling over the taller one? Also, how far below the roosts should the poop board be? Is 6 inches adequate, or should I do more like 8 or 9? Thanks so much for the help. All the information on here is SO great!
