I guess the question now is where did the breeder get the parent stock? It is posible that the parent stock or even a few generations back could have come from a hatchery. Every one has to start their flock some where. Some folks start with hatchery chicks and some go through breeders.
Pause, re-direct
where did the parent stock BLOODLINES originate, should be the question. Any one can breed chickens, but it is many years of work to create a bloodline. True Delawares have traceable bloodlines. Hatchery Dels are often mixed with other breeds to get a Delaware look-alike, but not really a true Del. I have done alot of research since I started this thread and the only black markings that any Del chick should have is an occasional spot on the top of the head (not gender related) that fades quickly with age.
