What breed?

[SwampPrincessChick]

She hasn’t started laying yet, we got her at our local tractor supply. She’s the only one to look like this. They gave her to us because she was going to be the last chick that day. But it’s odd because we bought each breed we have in pairs or groups and she looks nothing like any of the others we have.

Likely she will lay blue or green eggs, and that will confirm her being an Easter Egger.

I'd guess prairie blue bell egger but can't remember if they can have slate legs or not
