Welcome to BYC. Glad you decided to join our flock. I don't think you will be able to get Rosecombs with carnation combs. As far as I know the only two breeds that ever have carnation combs are Empordanesas and Penedesencas. Please feel free to ask any other questions you may have. We are here to help in any way we can. Cheers.
