Runner duckling color

[GeorgiaMay0110]

I bought these as an assortment of runner ducklings from McMurray. Their color selections are black, fawn&white, chocolate, and blue. What colors do I have? My biggest question is what color are the 4 brownish ones with dark feet and beaks? I included a pic of one of those standing next to the yellow which I assume is a fawn&white.

My blue runner looked like the one on the left with the faint white patch on its chest. I would guess the other dark ones are black, the yellow ones are fawn, and the pale brown ones are chocolate. They are so cute!
