This morning at 6:30, I found a dead duck. Out of all my animals, she was the only one killed. Her breast had been eaten, and she had bite marks on her tail and back of one wing. There was a feather trail of about 15-20 feet, starting with little pin feathers, leading to the spot where the duck was found. Around that spot, some bigger feathers wer found. asI said, most of her breast was eaten. There were no flies on the carcass at all, so I am assuming it happened probably minutes before I awoke. ( I spotted her outside my bedroom window). I didn't check to see if she was still warm though. All my chickens free range, as do my ducks. But she was the only one taken. And please I don't need to hear I anything along the lines of--you shouldn't be free ranging blah balh. I knew the risks, and in four years this is the only time. What I am looking for is help identifying the predator, so I know how to take care of it. Predators known to be in our area are--racoon, oppossum, great horned owl, coyote and fox. There are mink and weasel also, but I know it wasn't one of them, as from what I am told, they chew off the head and suck the blood, and kill many animals as they can. Any ideas? I'm sort of leaning to raccoon, but not sure. I bought a large size live trap. But need to know what to bait it with. Any insight appreciated.
