A 12 pack Avery Oversized Mallard Shell Decoys is the perfect duck decoy for big field spreads!  Different from other duck shell decoys that are just duck decoys with the bottoms cut off, these duck decoy shells are full body ducks so their body gives the full effect from anywhere a duck can see them. They stack great so you can store and haul up to 4 times more decoy shells and the seamless design makes breast splitting impossible.  This is a 12 pack Avery Oversized Mallard Shell Decoys that includes universal Motion Stakes. This 12 pack includes 4 Semi Active Drakes, 4 Active Drakes, 2 Semi Active Hens and 2 Active Hens.
