Thank you for your input! I'm so heartbroken, they are all so lovely. Statistically speaking, what are the odds I'd choose all cockerels and good to know about colours! Most EEs I see are more beige.
The odds even up over enough birds, but it's awkward when you get on the wrong side of the statistics.
EEs can come in any color and have any appearance -- their one defining characteristic is the blue or green eggs. Though some birds sold as EEs don't lay blue or green -- they just have a bird who laid that color somewhere in their ancestry (I don't approve of hatcheries selling EEs that didn't hatch from colored eggs, but that's how things are).
