We have a similar set up and are just now installing the poop board and roost. It is about waist height and with Jersey Giants they definitely can't be allowed to jump down from that height, so we are going to try to put up soft wire or chicken wire like a wall in front of the poop board so they cannot jump down. It will force them to have to use the ramp. I don't know how that's going to work out, but we really don't have another option. I am hoping they prefer the 'extra safety' feeling being behind a barrier!! 
We'll be using a thick dowel (2"+), but we are currently using a thick tree limb and they love it.
