I have 10 older birds 8 hens other than the babies. One looks just like the babies I have she lays mint green eggs. Her "ear lobe" is the same color. I have no idea if that is a way to really tell but maybe the others will pitch in. If there was a real way to tell my guess is I would have found it. I am in the EE group, ameraucana group etc. There is no way to really tell before they are mature as far as I know. I will see what I have for photos.
