It is very unlikely that you could catch a coyote in a Hav-a-hart trap. They are very smart and cautous.It knew your dog was not around otherwise it would not have attemped to grab your chickens. Since you have a dog, snares and leghold traps are out of the question.Thanks. It did get everyone in the tractor. When they free range I'm out there with them, but I thought the tractor was solid enough. We're re-enforcing the big run and waiting for DEP wildlife people to call us back. They say we may not be able to trap it. I find it hard to believe that the guy in Colorado could legally buy all that amo and assault rifles but I can't put out a havaheart trap!
