Quote: For a book, Genetics of Chicken Colours is excellent in explaining the different genes in layman's terms. I don't know if you will be able to find a copy though. It's an expensive book ($100), and was close to out of print last I heard. Check at chickencolours.com. For a website, Poultry Genetics for the Non-professional and Genetics of Chickencolors and Basics are good starting points. chickengenetics.edelras.nl has some great photos, and once you have a better understanding, goes into a lot more detail.
