My girls just started laying a couple weekends ago... for the first week I got an egg a day... then I started getting 2 and for the past few days I was getting 3. Yesterday, we got a 4th egg and it is olive-colored. We have a BA, lt brahma, delaware and EE. The other eggs have been sort a medium sized light brown, and a slightly larger lt brown/pinkish color. Which one laid the olive green one?
