Sorry to hear of Mr. Goose's demise, sounds like he definitely had a good run!
Geese truly can be fierce and fearless protectors. We used to live by a wide waterway and had several Emden geese. The Alpha male (who lived to be 12-13, best guess) would attack anything he felt didn't belong... even saw him attack the mail carrier's jeep, if he was parked too long!

Yes geese make very good protectors for chickens.
