:Ken, Double mating can be done for plumage type or for color, keeping separate male and female breeding lines-- at least two lines. There will be a dominant male producer in one line and a dominant female producer in another. It IS possible to produce both great males and females from just one line, but for how long? The next generation needs to be an "opposite" strong type for the standard production, to continue produce a male or female that can carry on the quality of the best. I think I cannot explain it in a short version. There are good references. One is: "Old English Game Bantams as Bred and Shown in the United States, Jeffrey and Richardson--a classic textavailable at most Poultry Supply catalogs. (not all is applicable to Dutch). And Jeffrey refers the readers to the Carefoot book "Creative Poultry Breeding". Let's hear from someone who can tell how they use it with their Dutch. Some of these things we do perhaps by instinct?????And then we find it fits a classic textbook pattern.
: For us "Beginners", maybe you could elaborate on the "double mating" concept. It helps to understand the concept when you can see it laid out possibly using genetic generation notation.
