I suggest you read his article again as Ken does not say what you have written. If you read his article on his website there is another article following it written by Paul Russ in which he says he has bred DF Dom Pieds without iris rings but neither author states it is a fact for 100% of DF Dom Pieds.
Glad to see you back.
Do you have a link to the article or Ken Yorke's website?
