Quick Answer
Set decoys in a J-hook, U-shape, or V formation with the open end facing downwind — ducks land into the wind and will approach through the opening, putting them in range. Use 1-3 dozen decoys for small water and 4-6 dozen for larger areas. Mix species realistically — mostly mallards with a few teal, pintails, or gadwall mixed in. Place confident decoys (feeders, tippers) on the upwind side and alert heads on the edges. Add motion with a jerk string, spinning-wing decoy, or ripple maker. Space decoys 2-4 feet apart in the main group with wider gaps near the landing zone.

Understanding Duck Behavior
Ducks approach and land into the wind, just like airplanes. They glide in low, scan for danger, and commit when they see relaxed, feeding ducks in a safe-looking area. Your decoy spread needs to look natural, provide a clear landing zone, and draw birds within shooting range of your blind.
Basic Spread Formations
J-Hook: The most popular layout. The long arm of the J runs downwind with the hook curving upwind, creating a natural landing pocket. Place your blind at the curve of the J. Ducks will swing around the long arm and land in the opening.
U-Shape: Creates a wide landing zone between two arms of decoys. Effective on larger water where ducks need more room to commit. Place your blind at the bottom of the U, centered on the opening.
V-Formation: Two lines of decoys extending downwind with the point aimed upwind. Ducks funnel into the V and land at the wide end near your blind.
Decoy Placement Details
Quantity: 12-18 decoys for small ponds and timber holes. 36-72 for larger marshes, rivers, and open water. More decoys create more visibility from distance, but a well-placed small spread outperforms a poorly arranged large one.
Species mix: If you’re hunting mallards, make 70-80% of your spread mallard decoys. Mix in a few other species for realism — teal, pintails, or gadwall. Add 2-3 goose floaters or confidence decoys on the outer edges.
Posture: Use mostly relaxed postures — feeders, tippers, and sleepers. These signal safety. Place alert-head decoys on the outer edges where real sentries would watch for danger.
Spacing: 2-4 feet between decoys in the main group. Leave 15-25 feet of open water in the landing zone — ducks won’t drop into a crowded area.
Adding Motion
Still decoys on calm water look lifeless. Add movement with:
- Jerk string: Cheapest option. A cord attached to a decoy that you tug to create ripples
- Spinning-wing decoy (Mojo): Highly effective for early season before ducks get educated
- Water ripple/wave maker: Battery-powered devices that create realistic water movement
- Wind-powered decoys: Swimmer decoys that paddle in the breeze
Common Mistakes
- Setting decoys too far from the blind — keep the nearest decoys within 20 yards
- No clear landing zone — ducks need open water to drop into
- Decoys too uniform — vary postures, spacing, and species
- Ignoring the wind — always face your spread with the landing zone downwind of your position
- Too many spinning-wing decoys late in the season — pressured ducks avoid them
