Canada geese that feed in frozen weather will lay down and later feed on the frozen ground they just melted. For hours they will feed, move to another frozen spot, and take a nap between thawing their feeding spots. When the weather gets colder and the season presents more hunting pressure, sleeper goose decoy shells will communicate an area is content and secure to flocks passing by. As the greatest benefit, these sleeper goose decoys stack for compact space efficiency and allow you the opportunity for larger decoy spreads.
