Cool! I once had a showgirl/frizzled-polish cross rooster and he was the cutest thing I've ever seen (taken by a raccoon sadly). I bet your frizzled naked neck silkies will look similar - very cute! When crossing blue and white, it depends on whether the white is dominant or recessive (or both in some birds). The rooster I mentioned was white (with white dad and laced mom). If it's only recessive white, then the babies would be split-white (appear blue or black with leakage probably). When you put those back with white though you'd get 50% white assuming all are recessive white only. If any of the birds have dominant white in them though you could even end up with some paint color. If your blue roo is split-recessive white (no way to tell until breeding), then you'd probably get 50% white, 25% blue, 25% black. You'll find out soon!
Thanks for the info! I am so excited to see what we get from him.
