Who produced that if I may ask? I ask, because I have never seen any documentation on Genetic ringers. There have been many Super Cinnys that have had ringer marks like that, or larger, but I love to see a ringer trait proven genetic. I don't believe that right now.
As to my favorite Cinny cross, I am a bit biased, because I work with them, is the Hypo Cinny. I have a shot at the Hypo Super Cinny this year, and hope I can hit on it. I believe it will hatch very orange, and develop a purple hue as it ages.
