I think I am missing some of this thread because it has already been edited but I now have my blue in with my splash in the hopes of getting 50% blue 50% splash and that the splash will not fade out to white.
I do have several mixed Polish chicks though, I did this to see what I might get for colors. Some of them are Splash x a red hen(probably a production red, red star ) and then some are a splash hen with several different roos (splash Polish, orpington, red cochin and a mixed salmon favorelle),I ended up with mostly black crested with white and black bodies but also ended up with a couple that were completely blue and a few with black crests and head and black/white and red bodies. A lot of them came out looking almost exactly like the appenzeller spitzhauben. Anyway, I find it completely intesting the colors you can get from Polish but I am not sure I have been very helpful here.
