Right now I have 22 large breed chickens that are all 13 weeks old, I have a large roosting ladder I made out of branches, but every night they all fight over who can fit at the very top which is a 2x4 and a metal fence rail that I use as my hinge to be able to lift up the roosts to clean under. I am thinking of changing out the branches that they don't seem to like for 2x4s. Any opinions? I have seen people suggesting both but my birds seem to like the 2x4 at the top. I know they naturally want to be as high as they can so that might be part of it, and I also have pretty uncoordinated boys in the group that have trouble on the branches. Here is a picture of what I have, the roost is about 5' high at the highest point and 7' wide. (the chicks were only 6 weeks old in the picture)
