Oh they're cute! The black and white (yellow, whatever. =P) looks like a magpie to me, but to be fair I don't know much about duck breeds. I duckysat some baby magpies not too long ago for a friend, and that's what they looked like, except without the tuft of fuzz. I have some baby muscovies due to hatch on the 23rd, so I'm getting my duckling fix. Congrats on your beautiful babies.
