The pictures are a bit blurry and the chickens in question a bit far away from the camera to make a good determination on breed. maybe take closer up pics?
I would say top one is Ameracauna or EE hard to tell from distance... bottom most likely a EE.... I breed RIR I dont think top one is.. If you canget closer pics it would help..)
The bottom looks to have a beard- easter egger. The top is a mixed breed. Certaintly not an ameraucana, no slate legs, wrong comb, no beard and muffs, not a color of an ameraucana.
