But sometimes you can get a better bird! Just like with dogs! Really smart dog breed + another smart dog breed = Genius canine. I can see how it ruins the genetics if a particular color fades out within whatever number generations, like if ya keep crossing splash to splash silkies it will fade out, but the bird itself does not change. It's still a silkie.
But heyy some folks are making khaki and chocolate silkies.. Or whatever.. Something new. Someone should make a chicken with a pretty purpley-red chest like rouen drakes have. I love the purpley-red chest, burgundy is a better word. Or just the burgundy color for the whole chicken. Burgundy and white!
I wish I could make burgundy birds!
