Missing Ducks

Well, our mother duck is done with her nest. Her babies hatched and she rounded them up and walked away. Did she stop to say thanks for letting me sit in your yard for over a month, here are the kids? No! She packed up and left without so much as a quack.

All she left behind was the cracked eggs and one that hadn't hatched.  By the time I got around to snapping the pic, something had eaten or at least taken the unhatched egg.
