Step seven: aluminum can shingles
Add some 1x4 boards or plywood under the roof to make a shelf area for storing treats and things; again, look at the gallery to get a close-up.
Now, just add shingles of some kind and it's almost done. Corrugated metal roofing looks best with this style of building, but any roofing material should work. I used experimental pressed beer can shingles for this project.
Step eight: add the perch
Finish up by adding a 2x2 perch inside the coop. A nest box is optional: the coop is so small that the chickens will pick a dark corner in which to lay eggs. Make sure all screw and nail points are cut off if they stick through the wood anywhere. Attach a pen or fenced area to protect the little birdies from predators like cats and foxes.
