I'm losing ducks about every other night. Last night it took 4. It's coming out into the middle of the yard to get the ducks. I have some younger ducks in a pen and the older ones (that won't get into the pen) cluster around it to sleep. I find either feathers, parts (the head) or an entire un-eaten carcass in the same spot, at the edge of where my yard ends and the woods begin. I don't know if that's where the critter is coming or going. May be a dumb question, but is that the spot where I should put my trap? I have other traps around the pen, but they are ingnored.
