All my girls are mixes. My first EE was a hatchery chick that was gifted to me by a family member and she layed a cream colored egg.

Quite the disappointment for all those months waiting for a colored egg that never came! She was also really skittish, I'm glad none of my current girls are particularly skittish.
I believe this girl is laying one of the blue eggs. I thought her eggs would be an olive color since she has the copper around her neck like an copper marans and she has a beard.

The lady I got the eggs from had both EEs and Ameraucanas, so at least one of this lady's parents where one or the other.
