I have fantastic waterfowl hunting in south eastern wyoming we have combo hunts on the north platte river for mallards and Canada geese. Also world class field hunting for canada geese in south central montana. The best time of the season to combine ducks and geese is usually late December or early November weather dependant. Licenses in wyoming are counter except your federal duck stamp which can be purchased at most post offices starting in September. We have great deer hunting but would be interested in swapping for a rifle and some pheasant hunting. Let me know what you think. Thanks.
