There is a problem with the wolves though. Wolves kill to eat, wolves kill to teach their young how to hunt, wolves kill for recreation. Out West outfitters are having to deal with the wolves brought into Yellowstone. Mainly the elk & mule deer population is suffering. The wolves chase the elk kill the young for all of the above. The cows slip their calves from being chased. There are to many packs & it is out of control. It is like farmers here dealing with coyotes killing calves. I have seen sickly deer over the last couple of years so maybe that will be the thing to thin them out?
