Black Sex link or Black Copper Maran?

[Redhead Rae]

Well to add some intrigue... she just laid her first egg and it was blueish-green. Beautiful color! But not a Maran color and not from what I can tell a BSL color either! What do you all think now? I'm totally confused!

She might be an Olive Egger (They come from a dark egg layer roo, usually a maran, with a blue egg layer)

She is appears to be a mix then otherwise known as an Easter Egger, or a failed Olive Egger.

If she had the genetics for olive, you would get dark olive eggs vs. the blue-green. That doesn't always pass down, so you can get lighter green-blue when the genetics for darker brown wash isn't inherited.
