Very nice. I'm still trying to get a couple Olives. My last 3 were all boys. I've got 2 in the incubator now so hoping for a girl or 2.
Unless my only EE I have is cockerel dominant then I may have to just keep trying.
@NatJ ... Can an Olive Egger lay blue eggs?
My original guess was Easter/Olive Egger but the thread title of laying dark green/blue eggs threw me off, hence my guess for Easter Egger only.
Limited knowledge here.
If you post some pics of your girl, the experts can give you an idea of what breed she possibly is.
I'm no expert but I'd guess Easter Egger.
Edit... Oops. Thought I was the first to respond. Slow typer.... 🙂
