Just because a bird is a mixed breed does not make it an EE. Your Roxie is not an easter egger, I would call her a barnyard mix. Are her earlobes white? And she lays brown eggs? Interesting, that's a good rule of thumb. I would also say your other hen is an EE mix, something gave her that color, heftier build (don't tell her I called her hefty), and yellow legs. The EE parent gave her the pea comb and green egg genes.
