Teal add a nice size difference in the spread. Add some ring necks too. Sometimes puddle ducks dont like to land over them so dont put them right in the hole. I would really try to match the hatch. More geese never hurts as well. Its better to have fewer decoys that are nice with some motion or action to them than a bunch that arent moving.

Its always duck season, there is just a long break from february to september.
