A very wide mix! Half of chicks will be NN, half not.. half will have the peacomb(does he have that?), half will have single combs, half will have beards, half will not..
If he inherited the O gene(that's the gene for "colored eggs"- either blue, green, olive, etc) with the pea comb gene you can reliably tell which pullets out of him and those hens will turn out to be colored egg layers, you could do OK with calling them easter eggers. If naked neck you could even call them NN EE. As for the rest..... some of the NN chicks will look a lot like hatchery stock turkens, especially those with single combs & out of the RIR, Lorp, Stars, BR.
The chicks from BR hen will be sex linked- black chicks without white head spot are females, with white head spot males. Do need to be sure they weren't Australorp's, as hers will be all black chicks in both sexes.. at the very least you will be able to tell any chick with white head spot are males and out of the BR hen....
edit- whoops, forgot the Orloff hen.. she will throw pea combed chicks, so that one will throw a wrench in using peacomb as reliable indicator of colored egg layers..
