its more about pest control than sport. yes, shooting is enjoyable and if you have shot all the fox in your area then there wont be any shooting for you in the future. but it will mean that no fowl is took from the farmer. although i dont think 1 shooter, or even a team of shooters could wipe out a fox population! although to be honest i think you should shoot a vixen before she has her cubs because its sort of like taking down 4 fox in one shot.
