I got 2 non sexed goslings about 8 months ago hoping they might be a breeding pair, and blessed was I. I raised them with 2 hen chicks to help them integrate and they are excellent watchdogs for the rest of the flock and I always know when someone is in my driveway. The eggs are very large. Fun stuff.
I believe it's broody
Good luck with that goose!
Excelsior!
