Maybe you could make a 2 stage ramp agains the walls. Figure out how long you need it to be. Place the ramp a foot from their close wall. Make a ramp from the roost running along the side wall all the way to the far wall halfway down. Then attach a second ramp to the bottom of the first ramp running along the far wall and ending at the floor. Good luck!Thanks @Chad Oftedal for the detailed info! It seems I am pretty limited on my 4x4 then
