Depends on where you live. In the United States, there are only bantams. In many other parts of the world there are both bantams and large fowl silkies. Periodically I hear of people working on large fowl in the US, but I've never seen any except in photos. The one I did see on BYC a year or more ago was HUGE--a 10 lb. bird! Far larger than is recognized in other countries.
