Wow....I'd forgotten about the Duck and the Chick. But that's a bit different. They were bred to be pets for people who just wanted a chick or a duck, not animals that were rescued after being hit by a car or attacked by a predator, etc. And if an animal is rescued, and can't be re-released, what's the difference between a rescued duck and a rescued dog, really? The duck did live outside in her pool area originally, I think, but there was something about this particular breed of duck not being native to Florida and they didn't know HOW it even came to be there, but there was some reason he didn't do well outside. And she had found a conservation place to take him, but the day she brought him there, some other ducks killed another duck of the same breed because it was an outsider..apparently ducks can be very territorial. They were worried about his safety, so instead she just took him back home and decided to keep him inside the house instead. And there are companies that make the diaper harnesses, so it must not be THAT rare if people can make a living off of selling them. Might seem a bit weird to you and me, but then I think it's weird to have a snake as a pet and there are lots of people who do that. To each his own, I guess. And now that I know her, yes, she's a bit eccentric, but she's very kind and sweet.
