We had two families of geese this year, one pair had five the other three. After I put the decoys out, the families avoided our property. After a week they left! They walked between houses & went into a field & finished raising the brood. The family flew back but still kept thier distance from my yard. I was amazed! The geese always came to my yard, I lost track of how many hostas they chewed & spit out. this year we have a vegetable garden next to the pond & they have not touched it. The aggesive decoy is a touch front heavy, so the smallest breeze makes him move.
