I have something coming up and taking my chickens after they have deceased. They have never taken or tried to take any live chickens. so my question is what comes up to my door and (outside the coop) and takes my already dead chickens, usually overnight? there is never any feathers or drag marks, so whatever it is did not eat it on the spot, but is large enough to carry it away and not drag it. I know we have both fox and coyote in North Central North Dakota, is it one of them or something else? I have not been able to see tracks and I have 2 live traps set all the time and have never caught anything. I would like to figure this out just so whatever it is does not try to get the live ones.
