In the longer term, life time of breeders, the number of breeder fowl is larger than the small number kept by a single breeder. Those relatively rare infusions of new blood and establishing new lines based on a battle cock (remember earlier I said that is seldom done) is what is needed to replaced alleles lost via genetic drift and inbreeding prone small breeding flocks. Their are problems to that system now. First fewer lines to outsource new blood from. Second, many of lines are derived from the same source only a few generations back. Third, the system of selection is not as deep with many breeders, apparent health and vitality under vary protected conditions removes some of the selective forces that used to operate on American Games. Finely, the infusion of oriental may be diluting some of the European traits that make American Games distinctive in a manner I think makes them valuable to the future of agriculture as a repository of alleles.
