Okay. At one time I had Black, Mottled, and White Javas. The Black and Mottled Javas were generally very healthy. But the White Javas hatched out very small and were weaker and developed slower than the Blacks. When they did reach laying age they layed quite well and were eventually just as large as the Blacks. However between 12-18 months generally I would start losing hens. I assumed the majority of these problems were from inbreeding. I have thought and thought on that problem and in my mind this breeding scenario would help but maybe I don't understand the genetics behind it. What I would do now if I had them was cross the White Java males onto Black Java females and vice versa. You would cross the offspring from that breeding to White Javas. Your F3 generation should have white birds and when bred back to White Javas they would throw all White Javas. I wish I could draw a punnet square on the screen to show the mating, but I will try to sort of do it. I hope it works. BB - homozygous Black Java Bb - heterozygous Black Java bb - homozygous White Java (has to be because two recessives) b b B Bb Bb B Bb Bb b b B Bb Bb b bb bb b b b bb bb b bb bb Now if the Black isn't dominant over the White then this whole idea is completely wrong. So all you poultry genetics buffs, tell me. Would that have helped add some new genetic material to my White Java flock? Is my theory right and at the end I would end up with White Javas after two generations or would I have been losing the white?
