Do they bond with poultry?
I wouldn't say bond as in become friends with them, but if raised with them they will tolerate poultry and not chase them, etc.
..... what’s the livestock guardian portion of emus? I’m super curious. I’ve always wanted one... you mean there could be a purpose?!
They kick and stomp things that they don't like - so small predators like foxes, raccoons, etc, are asking for death if they wander into an emu pen. They probably won't be able to protect from any large predators, like a pack of coyotes. But for small stuff they're a pretty good deterrent. Since I've got them the only birds I've lost to predators have been kept in a separate pen from the emus.
