Wynette , I believe that we can use any of the color variations from the BC when trying to breed a better bird. I have never seen any proven results where a person has done the test breeding to show that we can only use certain individuals for breeding. I have used the Straw and copper and mahogany in different test matings and found none of the results we have heard of on line. Really the only way we can know for sure is do the test matings with records to back up the results.
