Quote: "Blue" or "Splash" refers to the color of the feathers when they're adults, but if they're white rocks, they'll feather out solid white. One of my best hens is a white rock. I've been considering getting more, but I'm mostly hatching out my own right now.
If you do have white rocks, you got good chickens. Although it's impossible to say exactly what kind of chicken each individual bird will be, they tend to be friendly, intelligent, and solid layers, not to mention heavy-bodied if you're interested in butchering them. (Winnie is lucky she's our favorite, that's all I'm saying! lol )
