I have Ameraucanas and had one that I changed my mind on at least three times as it matured. Or, as it turned out, as HE matured. @Kiki knows, I posted pics. Acted like a pullet, still is low on the pecking order, but is an obvious cockerel by saddle, cape and spurs. Yes; I know some hens can grow spurs but the great majority don't. Put all three indicators together and boom- little roo.Pictures of the face are necessary, size and behavior aren't good indicators of genders
