16 x 12 Run

[Flipman]

I would like to find a building plan for a simple but attractive 16 x 12 chicken run with a lean to type roof.

There are many articles on building coops. Have you looked through any of those?

Check out the coop section using this link. I am sure you will find many worth taking notes on.

DobieLover has a nicely documented build. The run is larger than you are looking for, but maybe a good starting point.
