I can't think of any silkied chicken that had a long or high tail. Certainly the silkied Am roos had no long tail feathers. Perhaps it has never been tried, so I wish you luck and look forward to your reporting on this, and maybe pics if they do work out.Only if they retain the tail. That will be my biggest challenge apart from finding a suitable silkied breed to bring that feather into my line. No point in a silkied pheonix if their tail breaks before it hits the ground
