Somewhere is the mass of information at BYC I read it was better for chickens feet if they had a flat board to roost upon. I want my chicks to be as comfie as possible. Would a 1 X 4 be ok. I saw an interesting pic. of one roost that was like a flat rack of 2x4 , spaces inbetween the boards but all the same level. ? I am getting some J. G. and understand due to their weight should roost no more than 2' off the ground. What about the 1x4 's for rhe others ? Thanks
