Bathroom sink vanity dumpster find, you can see the hole in the back where the drain pipe came through the wall,
I built shelves with front for wood chip bedding, other side left open for feed and waterer. (pipe opening becomes door)
Set coop on 1/2 size pallet base, Simple removable roof lifts off for easy moving, Openings above doors are covered with hardware cloth (wire)
I added hardware cloth and wood ramp for daytime use, and theres a door to enclose at night with heat lamps in the "attic" area to keep the babies warm at night.
