For her mutation I want to guess recessive pied sky blue normal. I say recessive pied rather than dominant because the body color spot is rather low between the legs. But she very well be dominant, I'm not too sure.
Aurora is now her name. I had been looking for something sky related for her and also thought her name should begin with an "A". Once I had the "A" idea, I asked her about "Abby" and she thought it was OK, but not quite right. "Aurora" is clearly what we were looking for.
