Adopted by Goose

This goose has adopted my parents, and is attempting to establish residency in their cabin. We suspect it is domestic and escaped from its coop. It's a seasonal cabin and they're planning to close up soon. What should they do? Central Ontario. Near Bracebridge.

UPDATE: A neighbor of theirs is set up for chickens, so could accommodate a goose. And shortly after making that arrangement an ad appeared in the community message board. So the goose is going home.
