Such gorgeous birds!

Are these snowy calls?
Mean ol' Ricky! :/ Pretty little ducky, though! Well, all of them are.
I find it funny, though. Every time Crash gets a little too nippy, I insult his big nose, too, just to get back at him.

I'm relatively new to ducks, so I'm not sure if I have the expertise to help, but your little ducky appears to be at the same point in development as my 5 1/2 week old baby, Crash.

No idea on color, though.
Edit: I'm late to the party--but at least I had the same guess for age as everyone else!

Little victories.
