If you live boonie, in most states, YOU have a right to defend your livestock if it is being harrassed or attacked. It is drastic but terminal action on your part may be the only way. Once predators have learned to kill, they are VERY hard to retrain or to stop, usually impossible. Unless you are willing to foot the bill to adequately fence them out, if the owner won't restrain them, there are few options. A pack like you are describing may not all belong to the same person, compounding the difficulty of the "nice" approach.
