Hi Snake9987
Sadly, some foxes do kill hogs. Some people will say they eat happily side by side, but foxes are predators and cannot be trusted. It seems that some foxes become specialists in killing hogs – apparently they wait until the hogs unroll and then pounce. Obviously if the hog has become accustomed to eating side by side with a fox it will be more likely to be already unrolled.
There is also the problem of foxes damaging legs of hogs if the hogs don’t roll up fast enough. I have heard reports of young foxes playing with hogs and damaging their legs. There is a sad post in the Hedgehog Tales section where a poor hog had to be euthanased after having both back legs damaged by a fox.
I haven’t heard that foxes actually deter the hogs as much as, say, badgers do, but it’s possible. Are the fox cubs being attracted by food. If so, maybe if you stop feeding for a while, or make sure that they cannot access any food, they may not think it worthwhile visiting your garden. I have been lucky that I haven’t had foxes here and don’t envy you the problem. But, if the hogs reappear, at the very least I would try to make sure that wherever the hogs were fed are fox proof. They are more likely to be off their guard when actually eating.
Sorry not to have anything more positive to say. Good luck.
