An olive egger is a mix between ANY breed that lays dark brown eggs (Marans and Welsummers are the most popular) and ANY breed that lays blue or green eggs. Cream legbars, Easter eggers, Aracuanas, and a few others.I guess I should be asking... do they look like any certain breed? I mentioned olive egger because after we picked them out the man we bought them from mentioned they may be olive eggers.
With that said, we can't give you an accurate guess of whether it is an olive egger or not. It's a mutt, I can tell you that much.
