However, if that is not an option, either a llama or a donkey make excellent protection animals.
We have coyotes by us, too, and once a couple of years ago we witnessed our shetland pony run off a lone coyote that was lurking around the goat pen. We don't have the pony anymore, but fortunately we haven't had a problem of coyotes coming on our property anymore. My husband is an excellent shot. ;)
