I would make sure she has a goose house for night. Be aware of predators that would harm her. I have 2 geese and we used a large dog house that had not been used for years. We added a sort of screened in porch and added a gate (door) to lock them in at night.
If you can get a small kiddie pool for her to play in for now, until you get the pond, also if it's possible, a friend, another goose do she won't be lonely.
She looks like a sweet goose. : )
