I'm trying something new in the coop. Winter is coming and I want to swap out my tree branch roosting sticks with something a little wider that their feet won't get cold. My idea is to make a square roosting station so to say. I'm hinging one side to the wall and the other side will be held up with chains from the ceiling, thus when it comes time for cleaning I unhook the chains and it swings down out of the way. I have lots of wood scraps laying about so I'd like to just use that. Would it be ok to use PT (pressure treated) deck boards for the roost boards or should I just use regular lumber?
