Rosecombs have traditionally been very difficult to breed at the same level as the Single Comb. Many people suggest that it is linked to the Rosecomb gene. It pretty much holds true in every breed that comes in both combs. For this reason the Rosecomb varieties have not developed as large of a following for breeders that are breeding to the SOP. They did however have a following in the northern states for the advantage of not having to worry about frostbite in the winter.
