I'll take a stab at it, but I'm no Kev about genetics. The CL girls look very similar to the girls in your pic you are planning on mating him with. I would think the girls will look very similar to their moms, maybe a little added reddish in the breast or some barrs instead of "lace" ( I know not real lace but the patterning on the neck of your girls) on the necks. For the boys I have no clue.
Sorry, the photo is of Dumbledore with his little CL harem - no NNs in that photo. (Sorry if I wasn't clear). I have NN pullets that are red/buff with black tails, one that's partridge/black, and one all black.
