She is definately an ameraucana cross. The slate colored legs give me away. Did you hatch her? If her legs were pink at irth, EE, if they were dark/slate at birth, Ameraucana cross. Though I could be wrong but you can limit it down to slate dominant birds.
P.S. I looked up a possible color for her, if you had bought her that old, she could be the result of a columbian ameraucana project. Though the color is not admitted to the APA, it could be what you have.
