Avoid using medium or brick red females for breeding because this is not in keeping with the characteristics of the breed. Also, don't breed from undersized individuals or birds with black in their body feathers (called "smutt"). Black in the main tail and wing feathers is normal, however. Most Reds show broodiness, but this characteristic has been partially eliminated in some of the best egg production strains. The Rose Comb variety tends to be smaller but should be the same size as the Single Combed variety. The red color fades after long exposure to the sun.
