My son lived on some land with 2 emu’s. Coyotes were scared to death of them. When one of the emu’s died, the remaining one became a member of the flock of chickens on the property.
Go to youtube and search "coyotes and donkeys."
Raised and had emus in Florida, when we started a boom. Emus would enjoy a good shred of any possums or raccoons that came into their paddock.
Side note, if you snatch and grab an emu by the vestigial wings, and grab one close like you’re a Greek Gay Guy, you are safe from talons as long as you stay behind, hup two three four hup two three four/. Don’t let one spin on ya! SHRED your jeans.......
But don’t try that with a cassowary, that’s a bad ass emu that went to the Marines.
