There's ducks in my Backyard

So a while back, a duck found the top of a shed a good place for nesting in my backyard. Me and my step dad talked about it and we're thinking of raising the ducklings once they hatch.
We're building a pond and whatever else comes to mind that duckings would need.

Has anything like this happened to any of you before?
I fell dumb for asking , but is this a good idea to raise ducks from the wild as pets? (I've never heard of a story in the news where a duck has harmed a person before so...)
Has anyone raised a duck before?
What are your thoughts on this?

haha, if we really do this, I could probably post an instructable on how to raise ducks if this goes well.

Here's some pictures of the duck that's on the shed.
