I am very interested in the Delaware (and a few other heritage breeds too). Forgive me for being a new egg, but I have a hard time understanding when a bird is produced somewhat simply (New Hampshires and Barred Rocks) that it is no longer a hybrid. At what point does the bird cross the line from a cross to a breed? What determines this? If I have New Hampshires and Barred Rocks in my backyard, get smart and take a stab at this, select well and produce a Delaware looking chicken in however much time, will it ever be considered a "real" Delaware? Thank you. I really want to learn about this kind of thing.
