Thread: Black duck decoys are they worth it?

I'm certain ducks can identify their own species by colour. I've placed a few parry decoys in a spot of theor own seperate from mallard and grey decoys and incoming parries will usually land amongst theor own kind. I place my goose decoys seperately as well and ducks seldom land near those but the geese do. I tend to lay my grey and mallard decoys in mixed groups with strategic open landing areas between depending on wind direction to have the landing flight paths close to my zone of fire. I never call ducks close overhead.
