First Attempt/silly goose

So we attempted to take Our goose to the Greenbelt to set her free on Friday. As you can see in the video, there are plenty of goslings her age at the river. Despite some of our best efforts though(even hiding from her) she just seems to think she's part of our family. She didn't want anything to do with the other geese. In fact, she even tried attacking a mother and father who seemed to show interest in her. We love her, but I think she needs to be back in the wild with others of her kind. Especially since she's getting bigger, and she poops everywhere! How do you house train a goose? You keep her outside...that's what we do.
