x2 She's probably a Silkie mix. From what I can see her earlobes look bluish. Does she have 5 toes?
Love the silver duckwing color!
I say EE X silkie OR Favorelle X polish (many hatchery polish have blue ears) the egg doesn't look really green, or it could be the picture...I have gotten some off eggs like yours from hatchery birds before, and they're known to have some cross breeds and mishaps.lol
