Do Olive egger chicks have certain identifying characteristics. I recently hatched out a combination of easter egger and what I hope to be olive egger chicks (Ameracauna Rooster with Buff Orps, Black Austrlorps, Barred Rocks and RIR hens). The brown eggs hatched but i didnt keep track and now they are mixed in with EE chicks. Do I have to wait till they start laying to know which is which?Here is a picture. They are 4 days old.I do also have some BBS chicks in the brooder also.
