Most Araucana do not sport tufts. Tufts can be difficult to get. I have 3 tufted roos and 1 non tufted roo. Most of my hens are clean faced ( no tufts ) a few have tufts. Every tufted Araucana only has 1 copy of the tuft gene so sometimes they do not pass it on.
In my experience the bantam Araucana are really small, at least mine have been dinky. The large fowl are merely small. My roos tend to be decent size but the hens are smaller.
