My 5 foot welded wire backyard fence is not stopping the fox from visiting a couple times a week. I've recorded her on my cameras from midnight until 9 am. I've seen the fox in the front yard as well as the backyard. I am assuming it is a female trying to feed her kits for the fox to be out well past dawn. The fox hasn't been able to get to the chickens. The run is covered with a roof. There is hardware cloth on the sides of the run. There is a 3 foot hardware cloth apron. I am not letting the chickens out no matter what time of the day. I block any holes the fox digs under the fence but of course it just digs another hole. Yard is too big to add an apron. Was wondering about those predator repellents I have seen at the hardware store. Would the repellents help keep the fox away if I put the repellents around the outside of the fence? Hopefully someone here has tried them. Also, I have 2 small dogs. How safe are they going outside at night? Fortunately I have someone staying here temporarily who has 2 large dogs. I don't let my little dogs out unless a big dog goes out also. However, having the big dogs here is temporary. My dogs are 12 pounds each.
