I use the wife alert, she goes for a walk twice daily, 1/2 mile across 1/2 mile on dirt road and back. When she sees a coyote in the daylight it’s time to cull the herd. I leave the ones I shoot out there for a week or so before I go bury them with the tractor. seems to send a message to the rest of them. We used to have an old trapper that would drive around the area and keep the population down think he was getting $50 a pelt. But he passed 2 years ago. Make it a good one guys
