The Mallard Flapper is designed to give you natural motion in a spread. The Decoy is 65% of the size of a real Mallard. Small compared to adult Mallard but large enough to bring the Green heads in. The largest of the flapper line. Making the cost of making the decoy higher but worth it in results. So if you are looking to add something special to your mallard spread this year, this is the decoy for you.
