I no expert but really thinking you got yourself an EE pullet. There are a few hatcheries that do sell TRUE Ameraucana but most sell EE as Ameraucana

If you go online, search Ameraucana ....
Characteristics[edit]
The Ameraucana is one of the few chicken breeds to lay blue eggs.
[7]:11 It shows many similarities to the Araucana, including the pea
comb and the blue egg gene. It is tailed, muffed and bearded, whereas the Araucana in the United States has earmuffs and is rumpless.
[8] The earlobes are small and round, the
wattles small or absent; earlobes, comb and wattles are all red. The shanks are slate-blue, tending to black in the black plumage variant.
[6]:37
Eight color variants are recognized in the American Standard of Perfection: black, blue, blue wheaten, brown red, buff, silver, wheaten and white.
