Something killed one of my chickens last night and left only feathers and a wee bit of guts. We live far enough north that we don't have skunks or Coons. Our biggest concern is always bears and cougars...but this was obviously neither of these. So, what else would climb a six foot fence and take just one bird? Fox? Coyote? Wiesel? Ugh...we really do need a gun!
