I have a coop with a Black Jersey Giant roo and 2 White Rock hens. I am looking for a large, faster growing chicken that could be used instead of CX meaties. Six chicks hatched and are now about 5 weeks old; pictures were taken last week. Three (3) are all black with small, dark combs and black feet. The other 3 are barred (black and white) with larger, lighter colored combs and light colored legs. It seems like there could be a pattern here. Are the barred ones males? (Before I get to the pictures, I will admit that I have Cuckoo Marans in my flock. Looking at the barred chicks makes me want to second guess myself -- did I mislable some eggs? If you think the barred ones are really Marans, let me know. I do have more of the Jersey-Rock eggs incubating now. I need to get a larger sampling for my experiment.)

I'd love to hear what you think!
