As for aggression towards humans, I find the best way to establish dominance with gander is to pick him up and carry him around like a baby.

Also if it helps the best way to pick up an attacking goose is to grab their head as their coming at you, just firmly enough that they can’t get away, andwith your other arm scoop them up around the torso to also pin their wings, the faster you do this the easier.Longer than I can hold my breath for, that's for sure. No other geese, just these two and 4 laying chickens, which he doesn't seem to notice. They are 10 month's old. He's very aggressive with my husband too. He actually charges him when his back is turned. And our mail carrier won't get out of her car. =(
