The only fields in my area where ducks will come down would probably be corn. Dont get me wrong, you can see them in beans or wheat, but we kill ducks and geese in the same field, same day all the time. Usually, ducks come to the field just after shooting hour has started and geese always come after the ducks. Same for night, geese come before and the ducks come after, almost at dark. But I mean, if your in corn and your located near a marsh or a lake where ducks roost or what not, get yourself a mojo with a remote, ducks get sucked right down. dont forget to shut the mojo off before the geese come. One time we had about 45 ducks land in our cornfield about 100 yards away, way out of shooting range. We got up about a minute and a half later and the ducks were in are spread. when they land in corn, watch out its a stampede. have fun!
