If you got them from a hatchery or feed store, it’s almost a guarantee they are really EE’s and not Ameraucanas, especially if they don’t tell you which recognized colors and patterns they are supposed to be. You might look through this comparison, maybe at the soles of their feet or something like that, to help you decide. It’s way too young for me to do any good from those photos.
Just for fun, I’ll include this history. I find it fascinating plus it shows that a lot of the “common knowledge” on this forum about EE’s and Ameraucanas is just plain wrong. For example, Ameraucanas and Araucanas were developed from EE’s, not the other way around.
