So here are the better photos. She is crazy pants. The only chicken I have that is even half this wild. When I hold her she screams bloody murder.
Her feet look more yellow/pink to me. I have BR pullets and their feet are definitely yellow.
Pea comb.
As far as the ear, I don't believe a colored ear is a trait of a blue star. It is a trait for EE and PBB. The color kind of appears white, but is beginning to have a blue/green tint. She is not quite at POL, and anticipate the color will change as we get closer.
Her tail, almost looks like she could be a rooster. (Hinting at specific genetics) Her tail feathers are rounded, comb not red or large yet at 20 weeks, and no spurs/crowing.
Also, her posture is way different than any of my other chickens. She almost stands more upright and curious and holds herself differently.
