At first I built a chicken run, that was ugly and limited but very secure and predator proof. Early this year I decided to tear down the old run and install a new one, actually not really a chicken run but a coop extension.

Placed a coop in the top part of a wire clothed closed in area hanging on the opposite side of the hanging nest boxes and enclosed that coop in a wire cloth enclosed area mostly for inclement weather and protection at night against all the Bears, Coyotes, Foxes, Mountain Lions, and cougars that roam through our neighborhood.
