Indian runner color mixing

[melissa508]

At this time I have high quality white males runners, but no white females.
I have never had whites or mixed colors when ive bred them-
I have a really nice mostly chocolate female runner also- What could I get from breeding the choco female to the white male?.

There is no way to know unfortunately. White is a recessive "masking color" that covers up the other colors a duck carries genetically. What you would get in that breeding depends entirely on the colors the White has in its background.
