Jerry, good luck with your project. I had blue silvers in large fowl until this year. Just a word of caution. That autosomal red in your male could be a problem for many generations. It seems to be carried and passed on to their male offspring by the females - who don\'t show it in their own feathering. If your females are from a different line than the male you could get lucky though. If that happens, my advice would be to save a splash silver or blue silver to mate back with the old females. I would not even try using this male\'s pullet offspring as the odds are too great they will throw the red shoulders.
