Hi. Can anyone help with roost size and direction? Specifically, I am looking to buy a coop which has a 2X4 in its vertical position-- the 2 going across and the 4 going vertically. This doesn't seem right to me, but I have no chicken experience. In other people's coops I have seen a 2x4 placed on the diagonal or flat with the 4 going horizontally. If I were to get chickens of average size like Golden Comet or Black Star or Brahmas... what size of roost bar would you use and what side up? I might be able to re-position it. Thanks in advance.
