Is it ever possible to buy hatchery chickens and then work with them until they are good examples of a heritage breed? Or possibly they have to be from certain lines to be called "heritage?" Example: New Hampshire (currently heritage hatching eggs or chicks are extremely expensive) Cackle has some birds from something called the Newcomer line. ??? Can any of these birds be worked with for a 4+ years ( and selective breeding based on SOP and production also growing out quite a few birds) and then have "heritage birds" or no matter how great they look and come close to SOP (including weights), do you always have hatchery birds? I guess I'm asking if this is true: Once a hatchery bird always a hatchery bird.
