After my old coop got to small (see three bahama mamas in a tile crate) I upgraded my coop using a shipping crate for windows I found on a dump pile near a construction site. I will post some more interior pictures once I install my poop board and paint it.
So far I am loving it, especially the easier cleaning, because its kitchen counter height now, no more bending down!
