I have a couple different splash silkies growing out in the brooders. The older ones are around 3-4 weeks old. They are growing out a lavender type color, and the other ones are growing out white. Does splash have two different base colors, blue and white? I think I have read that before that they can either be blue based splash or white based splash, or something like that. Also when do the "splashes" start to come in on the birds?
