white patch

[Suezp]

Im a new duck owner, bought khaki's from Tractor Supply 2 1/2 weeks ago 3 ducks have white patches on their chest and three don't besides that they are all the same in coloring. Brown feet and dark bills why are they different?

Sounds like they may be Swedish, I have recently read that some don't have much of a bib - there is a Swedish thread you might ask on. Or, the bibbed ones may be Swedish and the others are the Khakis.
