I am doing my 4x4 coop today. We xed out the mega coop, so I'm building "The Mini". I'm stealing Steve's design (he don't know that yet LOL) and I have the base made. I was going to do wire, but eww wire, plus it's stationary, so I can't clean the poop underneath. I could use 1x6's covered with vinyl or osb covered with vinyl. Either is free, since I have the stuff. SOOOOO I should use vinyl? right? or no? OSB or 1x6's?
