Are feathered feet a "dominant" gene or can you breed that characteristic out? I have some "mixed" Columbian Rock pullets (clean legged and single combed) that I am considering breeding to a Light Brahma roo to work toward getting a real Columbian Rock (since I can't find any real ones here stateside). However I am concerned as to whether or not I can breed out the feathered feet? Also the pea comb....can that be bred out and replaced with a single comb? All you genetics experts out there.....can you help me out? THANKS as always!
