Dear God... what is it?

[Noah Way Farm]

This is an approx 14 week old bird I acquired as a "leghorn" from my local feed store as a 4-6 week old chick. Any guesses as to sex and breed? We also got 4 matching Hens, but this one was very quick to develop a rich red chest. Even though s/he was the smallest, its wattle and comb development exceeds the other 4, who have not even begun to develop wattles and combs are minuscule. All the birds have what I guess I would describe as slate/yellowish feet and legs. I have included a few pics of the bird in question as well as one of the other gems who is representative of the rest of the group. Oh, all of these birds were a solid mud brown when I got them, and now they are black with rich mahogany streaks.
Last three pics are the hen.

I wouldn't puzzle so much if the barred rocks this place sold me didn't turn out to be cuckoo marans, and a whole other bunch of black "mystery" chicks wasn't sitting in the other room. They order from Ideal, but don't keep any records and dump them all in a cage for you to sort out.

Sorry, I couldn't get the pics to post here. Try this link instead:

They look like black sexlinks to me.

Black sex link pullets

So my roostery bird must be a hen, which is why I was so confused.

Oddly, the "other" black chicks I have that I thought were sex links don't really look like these birds.
