My two year old gander has really gotten aggressive this summer compared to last. Breeding season this spring was horrible but he still will attack me even now. I've got so I carry a small rake with me in the backyard and he stays away when I'm carrying that. I've never had to hit him with it. The first time he came at me when I had it I just stuck it out toward him and he went running off the other way carrying on like nobody's business. So far its worked for over a month without any attacks from him.
