Wait, your Super Blue is a white chicken?I think its ee/leghorn . they are all white.
There are some called Arkansas Blue, that were developed at the University of Arkansas, but the project broke up and the birds were dispersed to various locations. I think some made it to the hatcheries. Those were a mix of Ameraucana and white production birds (similar to Leghorns) and they were blue birds with gray feathers. I sure wish they called one of those colors gray!
