Location is key. You have to be in the field the ducks are using or in a field on their flightline. Track ducks in the air or look for them working over fields, and be aware that ducks may feed up to 20 miles away from the roost. In northern states, ducks prefer corn to beans, but farther south they will hit beanfields. If you see geese sitting in a field, glass it for ducks. In warmer temperatures you can scout afternoons and hunt the next morning, but in very cold and clear weather, ducks will usually wait and feed once in the afternoon. On days with snow, sleet, and wind, it pays to be out there early.
