My DH pulled up this am and there was a coyote making himself comfy in the middle of our driveway! TOO close for comfort!! Did I worry about the kids on their way to the bus (ok a little) BUT he was near our chicken yard!!! Is there anything I can put near the entrance to the driveway where he came up? Do they avoid ammonia or anything else I can put on the ground? There have also been bear sightings in the neighborhood! HELP!!
