I have read several people use everything from 2x4's to small tree's dried. i suppose a chicken would pretty much use anything you put up to roost on, but i want something comfortable for my birds, may sound trivial, but hey, i like a comfy bed(roost). Do chickens "Need something small enough to grip, or would a wider, say a 2x6 turned flat give them something more to lay/squat on? If my birds are anything like me, one weird noise i would fall off a small perch... as i waited for a reply, just thought of possibly screwing a smaller, say 1.5x1.5 on top of a 2x6 if they need a foot hold, but it would still have the 2x6 under as a wider balance board...??
