OE is Olive Egger, and mine is a cross between a Black/Blue Copper Maran and a Black/Blue/Splash Ameraucana, based on what the breeder had and how she looks..
In any case, she looks exactly like a Blue Ameraucana, and the egg color is some very deep olive green. I wanted to cross her with the Black Copper rooster for even darker olive color, but the breeder, in addition to her chicks, shared with us a nasty thread of Marek's, too, which killed most of the birds I purchased from her (and some more).
I keep fingers crossed that the father is the Golden Cuckoo Maran (GCM) and the babies might produce nice eggs, too.
In any case, the chicks look exactly like their Olive Egger mom looked as a baby :), except their butts are yellow :).
The eggs look like the ones in the pic: the OE and the light cream color is the Lemon Cuckoo Orpington's (worst case scenario mix..). Unfortunately my GCM hen died in the same Marek's flare, so I can't compare the OE+GCM egg color possibilities..
