those ARE your chicks, or yours just look like those? Can you get some closer pictures? I believe that true ameraucanas have slate colored legs, not tan.
It's too early to tell. Where did you get them? True Ameraucanas are generally only available at a breeder. No fear: Easter Eggers are wonderful birds and you'll enjoy them just as much.
Your birds look like they'll be the common golden partridgey color many EE hens have. Adorable!
