Hello All, I am still in the planning stage of our chicken house. We will most likely be doing duel purpose birds (such as Orpingtons or Barred Rock). I have several questions about roosts. 1. How much roosting space is necessary per chicken (length of the roosts), 2. How far apart (both in height and width) should we put said roosts? (eg. 12 inches taller and 6 inches over...or whatever!) 3. What is a good starting height for the roosts? 4. Is there a good distance they should be away from nesting boxes to discourage sleeping in the boxes (something my fathers chickens do -and the poop is gross) Thanks Everyone!
