Dominant vs Recessive White

[TheChickenFanatic]

I have a question: I have a white satin showgirl under a splash rooster, and I've only ever produced white chicks under them. Granted, I've only ever hatched about 12 or so chicks from that pair. I thought for the longest time she is a recessive white, but I plugged it into the genetics calculator, and it looks like she is a dominant white? Could someone who knows genetics better than me chime in?

I'm not a genetics expert and I don't know how this pertains to your situation. But years ago, I had an ongoing issue with white feathers showing up on black hens after their first molt. Not roosters but only hens. I had a discussion with a poultry genetic expert residing in Europe. She mentioned something that stuck with me to this day. She said to keep in mind that white isn't a color but an absence of color. That fact did pertain to my issue.
