Alright, so this may be a dumb question, but I'm curious - how many traits are sex linked in chickens? For example, are different types of combs sex-linked? If someone was to cross a rooster with a rose comb and a hen with a single comb, would the cockerels have single combs and the pullets have rose combs? Or what about those ear tuft things (sorry, I know I sound uneducated, but I don't know what to call them) or the color of the chicken's legs? Are those sex-linked traits? It seems strange that people only use feather color/rate of growth for sex-linked chickens.
