Came home and found a duckling in my back yard. Upside down in the grass. Tiny little thing. It can barely walk. You can hardly tell it's a duck but, it has webbed feet and a little bill.

The thing is, there isn't any water around my house. No ponds, lakes, sinkholes, anything that would support a family of Ducks. It MUST have been dropped by a predator bird or something. It seems to be okay but, now what do I do with it? Raise it? How do I raise a duckling?

Raise it up to be a tasty big duck [:)]  Not exactly sure how to feed a baby duck.  Try chewing up some worms for it.
