You can't cross two different breeds and still call it a pure bred. Ameraucana and Araucana are two separate breeds, and Easter Eggers are more a 'type' than a breed. Your rooster is probably an Easter Egger, if he passes on a blue eggshell gene, otherwise, he's just a mixed breed.
Now, as long as he isn't barred or white, than the black chick in the picture likely came from a Barred Rock hen and is a black sexlink pullet.
There is no telling what the chipmunk chick will end up looking like at this point in time.
