SEMO, I totally agree that coyotes are just doing what they do best.
Having said that, would you agree that coyotes have adapted at much faster pace than in the past? Would you agree that they have LEARNED to hunt big game with efficiency, and therefore are more like a wolf in their behavior?
It is their "new" behavior that causes me concern. I killed three on Monday evening with a rifle. They were ALL sleek, and well fed. If you kill many coyotes with a firearm, you know that they often defecate when they are hit with a bullet. The scat is always full of deer hair.
The first coyote I ever saw was back in 1983. Few people EVER saw one during that time. Hearing them howl and carry on at night was VERY rare. By 1993, it was VERY common to see them and their howls were EVERYWHERE.
A single coyote in a hayfield was the norm ten years ago. Now, they are almost ALWAYS travelling in a pack. If you see one, there is at least one more close by.
I have learned to NOT be surprised by anything a coyote does. The only time I shoot at them is when I see them.
