Go with a guide and don't worry so much about killing but watch the ducks and listen to how he calls and how the birds react to the calls he makes. I watched all the videos I could find praticed everyday, and learned more in one morning watching two guys that knew what they were doing. Find someone that is good and TRY to talk them into letting you go WATCH no gun. You may have to be gagged bound blindfolded and wrapped in a tarp in the bottom of a boat to go but it would help you greatly
