what kind of duck are my ducklings?

[Chickenwolf]

A friend came by with 3 chocolate looking ducklings and I wanted to know the breed. He said they were the "Ugly Ducks" and he got them from another friend. But I don't think these are Muscovy.

I'm not a duck expert, but Muscovies come in many colors, and your blue chicks are looking like blue muskovies. Here's a link from feathersite: http://www.feathersite.com/Poultry/Ducks/Musc/BRKScobies.html
