I have one hen that is laying blue eggs(the inside shell is also blue). I got her from a local sale and was told she was an Olive Egger. She has blackish/grey feet and legs, has muffs and a pea comb. Could I actually have a true Ameraucana? What else will produce true blue eggs? I'm new to chicken keeping and have no idea and all the info on the internet is confusing me more. Here is a picture of her egg.
