As some of you know I built a roost with 3 poles. Each one is 54 inches long. For the last week I've been thinking I had them to close to each other. So I removed the middle one to see if the chickens liked it any better. The top one is 12 inches off the wall the bottom one is 18 from the top one. Last night those chickens were so bundled up on one end I could have put 12 more chickens up there. Does that mean I can get a few more for my space or should that space on the roost just be left void? I would like to get 4 more. I've found some layers close by for $10 each I would like to get, but I won't crowd um up on the roost. Thoughts?
