Let me set the scene for you.

There is a farm that I call coyotes on. On that farm they also raise cattle. The cattle are kept in corals (sp?) throughout the winter months. When a cow dies, they haul them off to a specific part of the farm.

I called two coyotes out of their den that was located less than a 100 yards from where the dead cattle were hauled to and not one of the 4 deads had been snacked on.
