most hatcheries sub contract out to local people so it would depend on what they use. I think that moat have an established flock of EEs to work with and don't have to outcross very often.
I don't think there are any Araucana in hatchery EE's. If so its very rare. Most EE's have beard and muffs which Araucana's do not have. Also Araucana's do not have tails and do have tufts ( not muffs) of feathers sticking out of their ears.
