What’s the best way to decimate a fox population? My friend lost 20 birds to foxes and there aren't many left. 9 out of 35. I know he needs to secure his coop, I’ll be helping him do that this week, but we need to kill at least some of em. What’s the best way? Cat traps? Shotgun at the den? Duke traps? Please help, he’s gonna not have a flock left by next week.
