These chickens are 16 weeks old. The male (top of photo) is a Golden Cuckoo Marans. What breed is the female (bottom of photo)? We got 100 straight-run mixed heavies from Murray McMurray hatchery in the spring, so it's been interesting to sort out the gender and breed. We received over TEN Golden Cuckoo Marans roosters, so I expect we might have 10 +/- GCM hens. Any ideas?
