Ducks may sometimes move on bluebird days, but your decoys never will. Moving decoys can add realism to your spread and create ripples that will make the rest of your decoys bob and appear lifelike even on the calmest day.

To rig a feeder decoy, you need two heavy anchors with rings on them (I used to use half of a pair of big gate hinges) and enough line to reach the feeder from your blind. Tie one end to the decoy as you normally would, then run the line through both anchor rings. Set one anchor beneath the decoy and the other in the water near the blind. By pulling the string you'll be able to make the decoy tip up like a feeding duck.

A swimming decoy makes use of the same anchor setup, but you'll need twice as much line, tied in a loop. Pulling in the top line will swim the decoy towards your blind. Pulling the lower line will swim it back out. Be sure to leave a clear path for the swimmer to travel through the rest of your spread.

The wake from the swimming decoy will not only rock your other decoys realistically, it will be visible to ducks high up in the sky who might not otherwise notice your blocks.
