Hi s1lversurfer, Firstly do you know if anybody is putting food out for the fox to attract them, many people do this so they can see the foxes, if this is the case, maybe a quiet word will solve the situation. If you know where the fox den is, would it be possible to erect a fence between the den and your property to deter the fox from coming near the house/buildings. You can buy a product called Renardine from most garden centres that you soak rags in and place the rags around the area where the fox is not wanted, I don't know what the situation is where you live and you may need to consult other neighbours before taking action. Do you live in a city or out in the country, would it be possible to borrow or even buy a fox cage trap, then trap the fox and then release it again, the fright would probably deter the fox from returning.
Its not an easy situation you have found yourself in and difficult to solve in a humane way, I wish you good luck.
