Olive Eggers aren't a breed so can vary immensely in appearance. Many times they have messy barring like yoursView attachment 2790732
She does kind of look like this one but after looking it up, I’m kinda leaning towards a poorly bred barred rock. I guess i’ll have to wait and see what color eggs she produces![]()

An Olive Egger is a catch-all phrase for a mixed breed designed to lay olive eggs. Some hatcheries come up with special names for them, but they're all mixes regardless. With her appearance I would guess part Cuckoo Marans and Legbar. Her eggs should stay similarly colored but with potential to fade as the laying season progresses
