I don't know who told lordmichael that wolves eat the old and sick but the answer he posted is in reverse order. Coyotes are far more prone to take weak big game species than wolves. The largest pack of wolves I've personally seen is nine. I watched a pack of seven take down four calf elk and two cows (Hamstrung the cows first) and take off without eating anything. I watched the kill site for three days and never saw them return. On the fourth day a cougar drug one of the calves off and hid it. So much for killing the old and weak.
