Wonder if that same method would work on a bird killing cat? Have a good cat. Kills his weight in mice,voles,gophers and moles, but he kills the occasional songbird, usually one of my Bluebirds. I've been mad enough to kill him twice after killing my blue birds, but he was faster than I could throw the hoe. Right now I put a #%^$load of bells on his collar to weigh him down and make his approach noisy, but he still is able to kill birds somehow...Use duct tape and tape the dead chicken around the dogs neck and leave it for a good while, like all day. They wont go near a chicken after that. Especially if you do this in summer. I broke a dog of killing cats the same way, after he wore that dead kitten all day in Aug. He never got near a cat again. If the cat walked too close to him he would leave.
