If it has green legs, it is an EE, because it would not meet the US standard for the breed. I think there are differences between Araucana & Ameraucanas in the US and Australia and England (?), but I'm not sure what they are. If the chicken is older than 7-8 weeks, I would say it's a pullet with that small, pale comb.
Thanks, she has grey legs and is 8 weeks old today
