She's an Austra White. As quoted from Dunlap Hatchery, "Austra Whites are a cross between a Black Australorp and a White leghorn. They are a breed that was developed by Dunlap hatchery in the early 1900's. They are an excellent layer of off white eggs. They are a heavier bird and a lot less flighty than a straight leghorn."wow she's very pretty, what breed?
