Theres SO MANY geese around where I am, they could raise it to 10......not even a dent. Juust a little north of me, theres those stick around all winter geese, THOUSANDS. You could use a dunkin donuts box for a decoy....they,ll come right in. Altho its hard to tell those birds from the ones usin the flyway, a dead goose is a dead goose. Another bird wont make a dent around here, heck...we cant even golf from them landin, crappin, or takin over the greens...RAISE IT
