Awww why does everyone have to hate on all the single comb girls? You know most good breeders will breed a single comb roo into their lines if they are having the infamous fertility issues which are carried on the gene for the rose comb. Yes, I know, I know, I speak blasphemy, but it works and the likelihood of having a single comb after a few generations is pretty low. Its ok to breed your girls you just can't show them.
