Need help identifying pullets!

We got these two at family farm and home, the one on the left is supposed to be a black sex link, and the one on the right is supposed to be an olive egger. Is this correct?

The bird on the left looks like a black sex link. Not certain about the bird on the right as olive eggers can have widely varied looks.

Olive eggers can look like anything. The one on the right looks more like a black sex link, and the one on the left might be an olive egger. I guess you'll know when they lay.

Thanks! Any chance that the top one could be a black copper maran?
