Well, from what I understand, the blacks that bleed through have partridge in their background. I'm not really sure but I would think that it would increase the percentages of blacks that you get in a hatch. Even as it is, I get almost 40 percent blacks and the boys are all rednecks... I'm sorry. I can't help myself with that term... That's why I have it on my profile with my avatar. LOL
But to be quite honest... I really know nothing. I have done what people have told me to do and the results have been, for the most part, outstanding. It has been such a great learning experience and I have met some absolutely awesome people that I am proud to call friends.
I do not know genetics AT ALL. I just know what seems to be working for me and will continue to do so.... It would be foolish for me to really experiment too much because I have a very small barn and not a lot of access to places to sell the birds. I am so far out in the middle of nowhere there's not a stop light in the COUNTY!!!
