In a previous post to you, I mentioned that one gene came from each bird. I am wrong on that statement. 2 come from the male and one from the female that she passes on down to only her male offspring. So restating this tells you that hereditory traits of the male will be more dominant in the offspring? The crazy thing about cross breeding chickens to acquire specific characteristics like color and such, is that you never know what lies beneath from a previous generation that could pop up at any time! When we cull out or select premium stock for breeding purposes, we try to strengthen the bird and breed to achieve a standard of what that breed should truly look like and perform.
Both of the birds you mentioned acquiring have features that you like, but are lacking one or the other. To me personally, body structure is more important than coloring. Use a good colored hen to breed it with and the color should improve in a few of your next male offsprings. Passing on characteristic features and traits is not a perfect science or scientists and farmers would have already created it! Truthfully, not many people attend or show birds to be judged for ribbons and bragging rights. Its more about keeping the breed pure and strong to avoid extinction from dying off.
