Not an easy answer middle ground here. A couple things, and these are just facts, no blame on anyone. Cattle have been domesticated and have largely lost their instinct and/or knowledge to avoid/combat predators such as wolves. They do have some instinct, but its just a little bit. This little bit is about the equivalent of a little bit of knowledge can be a dangerous thing. This little bit might actually make for the cattle being an easier lunch. They certainly can't compete with wild prey in avoidance abilities. Cattle let their calves stray a whole lot further from their mothers than wild prey animals, which make cattle easier prey.
Often individual coyotes become problem animals and can be effectively eliminated. It's said if you have coyotes but your livestock isn't harassed, don't kill the coyotes. Coyotes that ARE a problem will then move in. The wolves pose a bit of the same problem, but much mo ore complex. They aren't a single animal, and they are protected
A takings permit can be sought and utilized to target specific animals, but this is an entire pack. The question I have is this: Is there one or two animals (Possibly even the alphas) that are 'leading' this cattle slaughter? If so, could they be permitted and eliminated and possibly lessen the problem? Also, and I honestly don't know, What level of protection would guard animals offer if any if they could be present with the cattle?
