What's odd about the roosts? They are 4' long each, made with lumber lying broad-side so that they don't have to curl their toes. They are at about 2-1/2 feet and 3' height, offset a certain amount so that they don't poop on each other. There is a "window seat" shelf kind of thing running all along the wall above the nest boxes, under those two windows, because I know that at least our rooster liked to look out windows (though I don't know if the ladies will want to be up there or not).
I was wondering if they'd need a little boost-up ledge to get into next boxes. The opening is 20" above the floor. DO you think they need help hopping up into those?
