Thanks that is helpful. I have multiple girls that make SL's with my boy so am good there. Just wondering if the NH CL cross would be one of them...I really like your description and for me it will be helpful to know that the barring will still just be on the cockerels. I struggle with sexing and am constantly second guessing myself.
I think this would make sex links, just what I think of as "invisible" sexlinks....genetically the males will be barred and the females non-barred, but without the extended black, you're not going to be able to see a difference at hatch. You should know when the chicks feather out and you can actually see the barring on the feathers, but by then you've usually got a good idea who is male and who is female anyway. So, it's a useless sex link, IMO. The genes are there, but as far as practicality, they give you squat.
I think the auto sexing with the CCL works the same as with Rhodebars, and I know there are folks crossing RIR with Rhodebars to improve the type. It would take some research, but you might check out the Rhodebar thread and see if a RIR cock over a Rhodebar hen gives visually apparent sex linked chicks.
