We are a very large and very diverse country. There are many areas here where certain types of animals are extremely overpopulated and they need to be thinned out for the sake of the animals themselves, because overpopulation leads to disease and starvation. Foxes are one of those animals.
Personally I love foxes, we have a lot of them on our property and for the most part they are not a problem. But if they are desperate enough to risk coming up into my yard or coop area during waking hours, they will be killed, either by my dogs or my 22.
That is not uncivilized, it's actually very much like natural selection in action. Those that are apparently unable to survive well in their own environment get culled. If you truly cared about and understood the wild animals you would realize that while harsh, it's for the greater good in the end.
