I have bought two used above fridge type kitchen cabinets 12"deep, 15" high, 30" wide. I intend to remove the doors, create a bit of a small lip to keep bedding in and use it as a small community nestbox. I will make a hole in the back to that I can get to the eggs from the outside, through a hatch in the siding of the coop. The cabinets were $10 each at restore.
