Do what you need to keep you and everyone safe. I would contact the Bureau of Wildife and Fisheries/Land Management, or whichever the department is called in your state to find out the best way to manage it. Remember too coyotes are typically nocturnal so if there is a den, they may be nesting in there during the day if you try to do something to to the den; otherwise it could be a nasty surprise. Do some more research before approaching; want you to stay safe.
