"Emus get to be 6 feet tall and 150 pounds, so they are strong If angry or frightened ... If raised properly, they tend to be gentle and affectionate. They need a big enough pen to get their exercise, and the fence and other equipment has to be strong to withstand them. Also, their poop stinks."
Sounds about right.
We currently have 3 emus in the field next to our house. Pretty sure emus are misclassified as birds, they are dinosaurs for sure.
