In the middle of the day today I looked out the window and there was a coyote in our backyard/field. Not even 100' from my husband who was mowing. In the two years we have lived here we haven't seen anything and now that we have ducks a coyote shows up. That's just terrific seeing as how we only put up 4' fence around their yard. All we can do is put up a bunch of electric fencing and hope for the best I guess. If I bought a mini donkey would it be a deterrent or would a full size be better? I would happily let it roam all over if it kept everyone a little safer.
