I just HAD to have a checkerboard pattern on my poop boards. They were osb primed with 2 coats of kilz and then I stuck on squares of the stick on linoleum alternating white and black. It was so cute.............Until all the linoleum peeled off and the shavings stuck to it and it was a disgusting mess. So....We need new ones. For those just putting them in, a word to the wise. Don't mount them just below the roost bars. The chickens will sleep on them and get shat on by the ones sleeping on the roosts. Also make them much wider than you think. They sit facing forward and backwards on the roosts and they must projectile poop off those things. So what material did you use for your poop board and how did you attach the linoleum? Thanks. BTW, it looks nothing like this now. Not in a good way.
