We are rural I have used foot/leg traps too for another fox that had killed some of my birds. I used a body of a bird it had killed when I ran it off but it came back and I put the traps around the bird's body. I don't use the foot/leg traps anymore due to some of the people in our area dividing...
I used some old chicken we had processed that found it's way to the bottom of our freezer. It had killed so I trapped it and eliminated it. It killed my most special bird during the middle of the day while I was distracted.
