Medic, you have a very good point. I do like to use 2X4s that are rounded on the corners, but I rip them down to 2x2s and turn so the sharp corners are down and not roughing their feet. But being as soft of a wood as cedar is, it wears down so the grains do raise up, so to speak. I keep my roosts fairly low, one about 9" and the other about 18" off the floor too, so it is not a big impact on the feet, which is another cause of bumblefoot, that hard landing from having the roosts too high on heavier fowl like the Buckeyes should be.
