I have my son's old cattle show stick. When my 6 month bucklings decided that they could push on me, I started just swinging the show stick back and forth perpendicular to the ground between them and my legs, and wacked some boys on the side of the face. They didn't like that and stay a respectful distance away now when I am feeding. Most of them just stayed back without it hitting them. The effect was much different that when I tried slapping at them with my hands. I know it doesn't sound real nice, but they have to be taught to respect humans or they WILL be dangerous.
