Are Ameracauna chickens classified as medium or large chickens?

[bobsmith2002]

I'm confused by the multiple conflicting online descriptions of standard sized Ameracauna chickens. Are they considered as medium or large chickens?

I think there is only large fowl or bantam designations, correct? If so, they are large fowl. That being said, my Ameraucana is my smallest bird, but still LF.
