rebel870

I have a bit of a fox problem, I have 25 ducks and 8 chickens and the local fox apparently learned of this new buffet of fresh meat , i need him gone i know where he is most of the time (or ive seen him there) its in a very overgrown patch of about 5 or 6 acres of very dense thorns and small trees and such, the longest shot in there is about 10 yards all of wich is surrounded by forest on 3 sides the other is a cornfield i am hunting with my Remington 870 express 16 GA chambered only for 2 3/4 have game loads NO. 6 shot

I cannot place traps because i have dogs that would get caught and injured so all i am asking for is some tips or advice to get him

he also has no problem coming within 10 yards of the beck door looking for a quick easy meal in broad daylight I saw him that day and several other times he is very big so im assuming getting him could be hard as he did not get that big by being stupid

any input will be greatly appreciated thanks
