The next question that should of been asked would of been to see the breeding stock.
I know I'm beating a dead horse and you are happy with your birds but JIK there is someone new to the breed looking to avoid the common pitfalls.
They advertized them as amerIcanuas. That should of been your first clue that they weren't ameraucana but infact EEs. If people waffle on the name or spelling they have EEs.
