Swissys and coyotes

Im really on the fence here, and could use some advice.

I live in a fairly rural location, and have a big, muscular 130lb male Swissy.

I also have a flock of about 30 chickens.

For the last 4 days in a row, I've seen the same single male coyote circling my chicken coop. It's unfortunately not in a place that I can dispatch of the coyote, but simply shooing him off hasn't worked. He keeps coming back.

I'm considering sending my Swissy out to chase the coyote off. On the one hand, I'm confident that my Swissy can handle himself against a single coyote. On the other hand, Im setting him up for potential injury- probably stitches, maybe worse. The most likely outcome will be some enthusiastic BAROOOOOing and a scared coyote.

Any thoughts? Am I mistreating my Swissy if I use him to chase off this predator?
