I found these prints on-line and I want to know if they are from a real breed of chicken, and if so what breed? Do they still exist? The birds appear to be crested, bearded and have slight feathering on four toed feet. I don't know if their color pattern is a real chicken pattern or an artist's interpretation. The listing at the bottom is: Vintage French rooster print. Buffon, Georges-Louis Leclerc (1770) [Histoire naturelle des oiseaux planches coloriées sans texte. Any ideas??
