Okay...whew , she seems okay now but she was drooling heavily so I knew she was in trouble...
I normally throw homemade bread to the chickens and since the new ducks ran over too, the goose decided she was going to eat some.
I read on the internet before I posted my question but found nothing to help a goose that was choking.
So for the future if anyone knows, please let me know. It's scary when you dont' know how to help them.
Obviously something worked--maybe it took several minutes of drinking to soften up the bread so it could go down, or maybe she would have just forced down anyway. Sometimes helping does help, and sometimes it makes matters worse--but I do not know how to help a goose, and I do not know how to recognize when helping is needed.
