What breed is this hen?

[ChickyWhicky]

She was part of a flock that was gifted to us. The flock contained bard rocks, easter eggers, and sussex (no idea what else they had throughout the years). She is the only one that looks quite different. She is nearly all white with a few grey/black spots. Slate legs. Blue ears. Quite large. Is she just some easter egger mash up? I thought maybe some leghorn in there?
What are your best guesses??

My best guess would be Austra White. What color eggs does she lay?

Austra white seems right. Yep, I'm rhyming today.

This is a hybrid between Australorps and white Leghorns.
