We have always built roosts out of large branches/small logs in a ladder-type arrangement. Our new chicken house has a concrete floor and no exposed beams or studs. We will have at least 25 chickens in there, with some heavy ones like cochins and orpingtons. I am just not seeing in my head how this will work with no way to attach the roosts to the floor for support... I am imagining a LOT of weight on the roosts so i don't think a nail-it-to-the-wall-and -call-it-good approach will work. Should I build a free-standing support of some kind? Or maybe put the supports along the side walls diagonally and then attach them to that? That still doesn't seem like enough support, we always put our supports under the middles of the roosts, not just at the ends. LOL help me compute this in my head.
