I found the explanation of how the naked neck gene passes from one generation to the next on the Turken/Naked Neck Thread #1218 and #1227 I think. The first one is a chart and the second one explains it as a numbers game using colors. Anyway, I hope it helps, I now have some idea of what to expect when I hatch out the Delaware eggs. I house my Delawares and NN together. Same of the Naked Neck hens.
