I had an injured canada goose show up at my place a few weeks ago. It was either injured in the wild and decided to rest with my ducks or (what I think is the most plausible) someone had it for a pet, it hurt its leg and they dumped it at my place b/c of all the birds I have. It's very tame as in you can approach it and throw treats to it, and shows no intention of leaving. I have not penned it up or shut it in anything, nor do I plan to do so, but it never leaves my ducks' side. If it wants to stay and sit on the little pond I'm building then so be it but I don't want to force it to stay if its truly wild. I can say that so far, it has been very cool having it decide to live with us.
