Pros: Friendly, Interactive
Cons: Messy!
These are great little ducks we got ours when we bought a Christmas tree, why people selling Christmas trees had ducks I don't know but here we are. They are easy to take care of and run after us when we're in the yard they're great.
I had some that were pretty friendly... but then they realized that the pond was pretty removed from the house and turned feral.
I'd like to get some more some time. :)
