Ameraucana Coloration?

[PirateGirl]

Yep the second link lists
Ameraucana Black, Blue, Blue Wheaten, Brown Red, Buff, Silver, Wheaten, White
These chicks could be Brown Red chicks and thus could be Amerecaunas
BTW if a chicken fits the standard for the breed no one can say it isn't the breed even if it is bred differently. There are no lineages kept like with dogs.

We have people see our barred chickens and say "oh that's a Dominique" when in fact we have no Dominique blood in our flock. But one is not only barred but fits the size and body style of a Dominique. I have learned however to say "yep Dominique"

Some of the accepted colors are not solids, so I'm really not sure myself what they look like as chicks. Plumage can change so much as a bird grows. It will be fun for you to see how your batch turns out!

Are they going to appear partridge-ish?

Possibly. But, truly, there's really no pinpointing exactly how they'll look as adults. Which, in my opinion, is one of the breed's best traits. I'll show you a few of my EE chicks (who a little like yours in coloration) and their transformations just to prove this.
