She looks to be of the cuckoo pattern to me , and egg color is looking more like a hatchery Marans but the BRs range from pinkish to medium brown so ...........
From what I've seen , hatchery productions of these three breeds tend to loose the distinct barring patterns of the two and the cuckoo pattern is less distinct in the other . Body types become off , size is usually smaller , breed characteristics get lost .......... but egg laying abilities are often increased so that's a plus for the hatchery breds . If you're a fan of the Marans dark egg you could get a roo from some dark egged lines and easily get better quality Marans from her , or use an EE/Ameraucana over her to get sex linked olive eggers if you want and they would not be as prone to frostbite .
