Very true Beowolf. But knowing wolves they have moved on to greener pastures. we could mention to him to buy a dog also. Just activity and keeping the sheep in at night should be enough to deter them.
But if they are going to return they will in the next day or two. If we keep doing what we are then we might bag one if they do. I know in real life you get coyotes coming and stealing chickens you kill just one and the rest go home and tell about it and they go look elsewhere. You kill the whole raid party and the others how up again later.
I will look to the farmer and tell him that he has done enough for me by providing food. I am glad to have been able to help make repairs upon his farmstead to make his livestock and livelihood more secure. I wish him good luck on the rest of his days.
