I love Diego, but he is agressive towards my hubby and daughter. I just figured he's still a teenager...not even a year old till Easter(ish). He's never really hurt any one, just jumps up and kinda bumps with his feet, but he's also a sweety who eats from my hand. That's the only way he get treats, since he lets the girls snatch everything away from him.
Last week hubby bought me a new wagon (the Gorilla wagon, it's called), and I load it up twice a month with hay, and twicw a week with garden and weed clipping and lug it into the run. I rake the run while they follow the rake pecking at anything I uncover, then spread out the hay or weeds. He never bothers me except to come see what treats I brought. They all love the wagon and climb all over it whether it's full or empty.
He's only jumped me twice...once when I was silly enough to crow back at him, and once when I spooked a hen and she squawked at me.
