We always add a few snows to the edge of our goose spreads. The white stands out for a LOOOONG way and gets the attention of a lot of other birds too. If you are dealing with around 6 or less they are pretty easy to decoy around here (middle of Mississippi Flyway). Calling helps and I have seen mouth calling work also.
If you are seeing a group of 100, well just sit back, drink your coffee, and wait for them to return during the conservation season. That is when we put out big spreads, e-callers, etc.
