Very complicated genetics. I have no idea except according to genetic diversity can make them anything carried in their genes. Others here do actual breeding on purpose and will have answers to your questions. I just knew that my Gracie, being an "albino" (all white) carried white face and lutino genes, and my cock, Chip, was a certified Normal (wild colored with black, yellow and orange) would produce anything from Cinnamon to lutino to white face. I found generally they produced Cinnamon hens and Normal cocks. Only one chick in twelve (or there abouts) would be a lutino or a white face. Of the 22 chicks they produced through their life, all but one were Cinnamon and Normals. I had one hen chick who was a dark golden pearl. Unfortunately, she died in a flight accident when she was three months old.
