I have several solid white, black and blue EE's. All came from a hatchery. I have ordered and sold more than 500 EE's in the past year and I would say that solid white, is more common than black or blue. Right now, I have an order of 50 EE chicks and there are at least 5 solid whites. My older black ones are hard to find in my flock, I have a lot of Black Australorps and Black Sex Links, so the you gotta look close to find the 4 that I have. I almost always try to keep the solid colored ones from the chicks orders.
