Got the new perches up at about 3 feet and 5-week old chicks have decided that they prefer the perch to the floor huddle So I found some particle board shelving laying around. We were going to paint it and attach it to the wall under the perches with shelf brackets. I have 16 lineal foot of perch for 16 birds, though they are only using about 6 feet of it at this age. Anyway. How important is it to make the poop boards removable? I don't think the boards will lay on the shelf brackets too well unless we screw them down. Any ideas on how to make a removeable poop board with particle board and shelf brackets? Thanks!
