There is a good number of Mallards (200-300) and geese (200+) using a flooded portion of a wheat field, about a 100yd. by 20 yd. stretch is water. It was an old slough that the farmer tilled up and planted. I'm not sure if the birds are leaving to roost somewhere else because I haven't had a chance to watch them in the evening. I'm just wondering if I head in there in the morning if I'm going to push birds off that won't come back. I think if the ducks want in there bad enough they will work back, but I don't want it to be a one shot deal with that many birds if I'm just going to push them out. Is it worth hunting or do you think I should look elsewhere?
