I recently acquired a book from the late 1800s, filled to the gills with fascinating information of the time. In the profile of the breeds of poultry, it had a section on crested turkeys, with an excellent drawing. It said that they were kept only for exhibition, and that one had had been exhibited at a New York poultry show a few years before the book was written. The bird looked exactly like the American wild turkey, except that it had a tuft on it's head, which could be white or black. The birds didn't always have crested offspring. If there are any turkey breeders who know something about this, I would love to hear. Thanks!
