I have the same coop. The roost is just barely higher than the tray and nesting boxes, so I made a higher, removable roost from 2x4s. It's oriented the opposite direction from the original roosts, so all three of my girls can fit on it. View attachment 1429009 View attachment 1429011
Good idea. I may steal this idea. I might use 2x2s so I can make 2 and maybe slightly different heights.
