I don't have a picture but I have plastic organizer bins on a shelf. There is a wood frame around them that is just under the bin lip so they won't tip when the birds stand on the edge. I also have a door flap that drops to access the boxes from outside and the hole is tall enough to slide the box out with a chicken in it if need be (thinking ahead for broodies...) The way I've set it up, I could take the boxes out and make one big nest shelf but I'm trying it this way for ease of cleaning first. So far, so good! The girls don't seem to have a box preference which I found very odd.
