I'm trying to figure my chicken out. She was sold at the feedstore as Ameraucana but from the research I have done, feel more comfortable with just Easter Egger. Now I'm trying to figure out if I have a female or is "she" is actually a "he". I've read the comb of Easter Eggers should be pea combs. This is a single upright comb. I would like some feedback on this and at what age will I know for sure on the sex.
