I wish you lots of luck with that. IMO, fox are near impossible to kill. They move too fast for me to shoot. They are too smart for a live trap. You might have luck with a leg hold trap. And, they are smart. I had a fox decimate my flock one year, in the middle of the day. She killed 4 birds, wounded a few more. She'd have killed all of them if we hadn't come home in the middle of the afternoon. Dead and dying birds laying all over the place. Brazen, evil creature. Would come back all hours of day and night, knew where the buffet was, continued to try our defenses even after we closed everything behind electronet. She'd hang out under the bedroom window where I had a dead body staked, and at one time, she was within 10' of me, staring me down. I was never able to get gun sighted on her in a safe place to shoot.
