Ameraucana come in only a few very distinctive color varieties. All have slate legs. It can help to familiarize yourself with the breed so you can avoid being fooled. Easter eggers almost always have green legs.I was just giving you my 2 cents.
I don't claim to know much but I too got all excited about Am's only to find out they were EE's.
The internet is full of experts, liars and just plain dummies.
