I am wondering what breed my hen might be. She was sold to me as a Blue Laced Wyandotte. She lays dark gray eggs/ greenish gray eggs.

Looks like an Easter Egger to me.

The colour of the egg upper right is interesting, who laid it?

The one in question, Violet. I think now she might be an Olive Egger

She does appear to be an Easter Egger/Olive Egger - for sure not a Wyandotte of any sort.
