Like most people I started with Easter Eggers thinking they're the same as Ameraucanas, then started my first Ameraucanas with several small flocks/lines of Blue, Black,and Splash birds. They averaged from poor to decent layers, temperaments were okay but slightly shy. The boys were GREAT though, always friendly and talkative but a bit of drama queens when it came to handling. They don't freak physically but they make a slight screamish sound, it's kinda cute.
I then expanded myself into Wheatens, Blue Wheatens, and Buffs after the BBS flock and got into much more friendly, better layers of even brighter blue eggs. Loved them.
In general I think Ameraucanas are an awesome breed, but the confusion of them vs Easter Eggers gets almost tiring in that so many people just don't fully understand what you mean when you're describing them, and the other thing is, I shyly have to admit - Araucanas, the other blue laying breed, have much more desirable characteristics for me. That doesn't make Ameraucanas "un-cool" though, as their having a tail and more availability is nicer, plus their Buff color is just amazingly beautiful.
So in the end my thought is always this - ANY flock must have, if not an Ameraucana, some sort of colored egg layer, but honestly I think Ameraucanas need more recognition out there than their much confusing rival, the Easter Egger. If not a neat blue egg layer with great cold tolerance, the roosters especially make wonderful pets and show birds.
