My husband enclosed my run by digging around it 8 inches or so, and cementing in the 1" sq 14 ga wire fencing with 4 x 4's 4 or 5 ft apart and the same fencing on top of the run. The screened windowns on the coop are covered with expanded metal. We have raccoons too but all they've done so far is eat my wild bird seed and the marshmallows in the live trap. My husband hauls them about 15 miles away to a place called Brushy Creek.
