Welllll...., I'm an amateur myself when it comes to calling ducks, but I'll try and help if I can. When blowing the feed call, stay away from the chucka chucka chucka sound, this ain't natural, ducks do not make that sound. A feed call is a series of extremely short quacks, go to the park and listen to tame ducks feeding and you'll see what I mean. Try putting the tip of your tongue to the roof of your mouth and saying zz zz zz zz while blowing short bursts of air. This is the best way that I know of how to explain it. Maybe someone with more experience will reply and either confirm what I've said, or corect me and you both!<img src=icon_smile_big.gif border=0 align=middle>
