We raised Emus, Never met a mean one unless you get right in their face in an aggressive manner as a real threat. They are indeed NOT a herding animal, unless you actually train them to herd with a wheeled cage you push around like a wheelbarrow when they are young, it’s almost impossible. As a natural defense habit they run back at you and then dodge around you like a football player carrying the ball avoiding your tackle. We have actually had to herd them in the wrong direction on purpose to get them to go the direction we really wanted them to go. lol
That’s what they wanted you to think, in reality they are planning for the next war...
