I figure it just makes things more definite to know if we're working with the Silkie feather gene or something else. Either way doesn't matter or change the process much, we would just know more than we do right now.
Since we don't have any laying AMs for Julie at the moment, there isn't much else to do to kill time while we wait for chicks to mature. Might as well.
I've had the very same conversation with many breeders. Just try it and see. They choose breeders based off of what they need for their specific program. That's not always the bird someone else might think. Sometimes the bird works out well, sometimes not, but they don't know until they see the results. I know where we're trying to go and we're lining up the stock to get headed in that direction while we wait. We expect to have plenty of culls along the way.
