Handling a roos like that is tough, they all tend to take care of the ladies though. If i had some prize winning roo that was aggressive to kids I would give a kid a stick and five dollars for every smack he landed. Otherwise, here comes the machette. How you handle your birds doesn't make them mean, they were born to it, some have to learn that my hands around your neck and my knee in your back is going to happen if you attack me, then I'm going to drag you by the feet with your head bumping along the ground, to your own private cell. They don't forget it, but they tend to recognise a newcomer pretty quick and go after them...now, do you want to be sued for your roo going after a visitor?
