Your supposition that a rose comb in used in making Cinnamon Queens likely faulty.
I've had all kinds of red sex links and have never seen a rose combed bird, not even in subsequent generations. On the various hatchery websites, all kinds of statements are made about which birds were used in making them. I've seen Rhode Island Red over Rhode Island White stated lots of times. Do those claims hold any water?
The problem is that the supposed "RIR" is typically a production red, which means he likely has Brown Leghorn blood to boost production. Secondly, the Rhode Island White is virtually extinct. If all the hatcheries that claimed to use RIW in their sex link parent stock likewise sold true Rhode Island White, then there might be some element of truth in the statement, but almost none do. Further, whenever some hatchery does show the supposed Rhode Island White, guess what? A single comb!!! Marvel of marvels, as the true RIW has a rose comb. What hatcheries use is most likely a silver/white bird of an unknown (to us) mix.
Bottom line? There are no breed police running around, so the hatcheries can say just about anything they want to say about what a Golden Comet, a Cinnamon Queen, a Red Star, a Golden Buff, yada, yada, yada. It's mostly just marketing. The word "breed" is thrown around far too freely.
