That's a good point yodeldog, that just because a coyote comes and you shoot, no matter if you kill or not, it's a good habit to keep calling, especially if the first coyote showed up with in the first couple of minutes. Les Johnson has some footage of a stand that they kill 4 coyotes, and each coyote came in seperately, over the course of about 20 minutes. In other words, a gun shot does not mean that the stand is over.
