Just a random question that popped into my head, have any of you guys tried attaching natural wings to your decoys? A lot has been said for the bird's ability to see light on the U.V. spectrum and those bright blue patches on a mallard's wing must serve a purpose in drawing the attention of other ducks. I think it might be a worth while experiment. I wouldn't go full stuffers, just the wings. I thought about how I've seen times where just one or two ducks that are outside of my spread draw in other ducks without doing a thing. You can have a killer looking spread with motion and a good location and they will still go to that single or pair of real birds.
