I own Araucana and Ameraucana..they are two separate breeds, not mixes. I also own EEs.
My Araucana are VERY broody girls..just about everyone broods at some point in the year. I have been fighting hens all winter and as fast as I break them, more go broody.
The araucana will snuggle on anything you put under them, including your hand.
I had one hatch out turkey poults for me once as well.
Here is my Quetros Araucana (tufted tailed) hen with a turkey poult looking out from her backside.
I also raise silkies and have found my araucana beat out silkie broodies big time.
My Ameraucana are more seasonal broodies and have not gone broody all winter, but they are major broodies in the spring/summer. As a matter of fact, I think one of my most broody in that pen is beginning.
Here is a good close up pic of a few of my bantam buff ameraucana..
I have an EE hen that will go broody once a year and an Ameraucana in that pen as well that likes to brood. None of my other EEs will give an egg a second look.
This is Amelia my black ameraucana (housed with EEs) who likes to brood:
