Hey Pokey, wish i was closer i would rid you of your problems, whether you free range your chickens or not..
fox are really not hard to catch in leg traps.
If you have the basics of trapping its really not hard to do, you just have to be very clean in how you handle the traps and sets...traps must be boiled and dyed and then waxed and always where rubber gloves and boots when handling the traps and making your sets...sets are the key to catching them if made correctly
Another thing to remember if using the "proper leg traps", animals can be put into dog crates unharmed and moved after trapping them in leg traps..
Just this week i released 2 small possums and 1 small raccoon onto game-lands up on top of the blue mtn far away from any homes or farm, as i felt they where to young to dispatch.
I do and will trap for local farmers and home owners close by me if the need help..free of charge of course..using box and leg traps..
