The best advice to give maybe this .... learn the ducks you want to hunt! You know the park where everyone feeds the ducks bread in the summer? Go there. Listen to the ducks, watch what they do. Learn to copy every noise they make. When do they make that type of noise? Is it while they are feeding? How are they landing? Are they staying in a group? What are they feeding on? What way is the wind blowing ? Are they out of the wind or in it? Lots of questions with lots of answers. Remember the ducks in summer that aren't scared of being shot at, are acting natural and calm. That is what ducks want to see and hear when they swing toward your decoys. Make them believe all is well and then all you'll need is the best advice on how to cook them good luck
