It's the eatser egger. Because you don't own an ameraucana.
The rest are brown layers.
Edit; I now see you also have a white ear lobed hen unlisted in the opening post. It's from her.
They're not genetically linked but most white egg laying breed standards also call for white earlobes.
It's still an EE tho, not an ameraucana
