There are two types of Cinnamon Queens offered by the hatcheries. One is a regular red sex link, but there is also one that is also sex linked, but looks a little different. This type is made by crossing a Rhode Island Red rooster over a silver laced Wyandotte hen, and that's what you've got. Wyandottes have rose combs, which are usually genetically dominant over single combs, so that's why this type of CQs mostly have rose combs. Confusing, I know, but that's what's going on with your hen.
