Hi there, about 5 weeks ago I had some purebred Dark Brahma chicks hatch out. One small, normally colored dark brown hen hatched out exactly 5 weeks ago. 5 weeks from tomorrow the second chick hatched out, although he was purely white... Could this be some kind of gene mutation that went on inside the egg? Now he is older and he has a nice little comb coming in BUT he has black, a lot too, coming in in his neck and tail feathers. He has black in his wings too. So- a dark brahma with light brahma coloring????? How would this happen? I will get pictures of his mom, dad, sister, and him later. Although I have heard of cross-breeding in hatcheries, I doubt that is the cause. Please reply if you have an suggestions!
