I was fiddling with the waterer in the run and the girls were bummin' around, not really intent on roosting yet, when I heard a hen bawk loudly. Usually they aren't very vocal so when she did it the second time I went out and saw the fox across the driveway in the other yard. Big fox. When he saw me he moved off so I hopped the fence and chased after him, yelling like crazy. I never let the girls out before 10 am and this was at about 6 pm to 6:15 when they were just getting starting to think about going to roost. Usually I let them roost and then go out at 6:30 and close the door. I certainly didn't expect to see a fox when it was hardly dark yet but there he was. I don't want to kill or trap him so I'm thinking a hot wire 6 inches off the ground around our 4 ft wire fence might do it. It is about 1/3 to 1/2 an acre. Or should I use another wire at some distance above the first one? It was just luck I was out there at the same time the fox was. Even when the hen bawked the others didn't do anything to react.
