My current nest box consists of a cardboard box on its side, with hay in it, on the floor of the coop. There is no way a chicken would ever sleep in there when there is a lovely roost 2x4 about 3-4' higher in the coop. (The whole coop is on the second floor of the barn so everything is up high, compared to the outdoor run. My chickens do go inside and up a flight of chicken ladders to the coop to lay.)
Don't feel your nest box has to be some formal, well-constructed design. They just need a little cubby place with some hay. I'd detach those nest boxes from the wall and set them on the floor of the coop.
