My brother and I found three adult ducks walking through my neighborhood as a kid. Strange, because there's not even a lake anywhere nearby. We fed them and kept them. They liked our wading pool, so we sunk it into the ground and built a pond.
The 3 ducks all looked completely different. One was a Mallard (beautiful), another was a hybrid Mallard (looked more like Daffy Duck), and another was a white farm duck. We named them Bobby, Pesto, and Squit.
A long time later, some neighborhood dog killed Squit. We took the other ducks to a lake far away.
