X2This is incorrect. Cubakid is right. According to both the American Poultry Association Standard of Perfection and the American Bantam Association Bantam Standard, Rosecomb bantams are only allowed to have rose combs. The general disqualifications in both the APA and the ABA Standards both have comb foreign to the breed listed as the very first disqualification. Neither one even lists a carnation comb, whatever that is, as being allowable for any breed. If a single or a walnut comb, or any other than a rose comb appear in a Rosecomb bantam it is certainly not "APA approved".
