Hi, all! Been super busy with classes, but I got a notification that I was mentioned in a post, so I thought I'd stop by and reply.
So you know,
dominant white causes white or yellow chicks, but
recessive white chicks are often silvery, smoky-colored, or even splash-like in appearance. I actually knew of someone who thought they had a splash Cochin rooster from two blue parents because he was splash-colored as a chick, but he feathered in without splashes. He was bred to black hens and produced black chicks, which is impossible by what is known about the blue gene in chickens (splash x black should produce 100% blue chicks). Anyway, long story short, come to find out he was recessive white.
Obviously, if the chicks feather out with any other color on them, then another gene is to blame for their color. Though recessive white chicks tend to be off-colored, the adults with recessive white show no other colors. Unlike dominant white, which tends to be 'leaky', recessive white covers completely on adult plumage.
(And yes, the chicken calculator is fun to play with. I may or may not pull it up out of boredom sometimes.
