Cullen, I have geese issues as well. A few non-shooting strategies may help:

1. Shift some feeding to night, especially after midnight.

2. Feed smaller amounts, but more frequently. My experience is that the fish start feeding first, then the geese crash the party. Smaller amounts tilt the advantage to the fish, less left for the feathered thieves.

3. Search for sinking feeds.

4. If legal, addle the eggs. The only thing worse than six geese is twice that many!

Like you, I can't shoot the geese without causing a bear market in the domestic tranquility index, but these strategies seem to help. Best of luck!
