What breed is she?!?

[Frazzemrat1]

What company did you get her from? What assortment?
My Pet Chicken sells an assortment that has a bunch of crosses to get dark eggs and to get colored eggs.

I just think she is beautiful, and if the dark egg is hers, enjoy your good fortune.

Help still trying to figure this hen out...she started laying some pretty dark eggs...her egg is pictured next rhode island, australorp, buff orpington, a leghorn, and cream legbar eggs. It's actually a bit darker than the photos show and now I'm extra confused.View attachment 1618812 View attachment 1618813 View attachment 1618814 View attachment 1618815

Brown Old English??

She looks like a mix to me, I don't know if that is possible due to where she came from but if it is i'd guess marans/speckled sussex. That egg is too dark not to have marans in the mix somewhere.
