I don't know for sure. Understanding the genetics (as written in books and webpages and modeled by the calculator) seems to be much easier than seeing how they apply to real chickens, especially when they are mixes of mixes!But that does leave me with a question... Why does Vadakor have Crow Wing when the calculator doesn't show that as a possibility...I might reach out to the guy I got Vadakor from to see if I was miss informed about his parents
