Pack behavior is for sure a problem with coyotes, a single coyote will rarely go after a calf but a pack will really get after calves. I have seen coyote packs attack a cow having a calf, not a pretty sight.
People in rural areas used to routinely kill coyotes to keep the numbers down because of the pack mentality. Now most people don’t understand nature so think coyotes should be left alone.
People moving to rural areas are even known to feed coyotes, skunks and other critters... a really bad idea.
We have skunks & coyotes here. So far, the coyotes have
been timid. I think when they breed with dogs, it results
in a bolder animal. - Skunk was coming up on our back porch,
rubbing noses with out big dog at the door of her doghouse.
Dub howls with the coyotes; she seems to know their
language.
