Sand Hill Preservation has white Ameraucanas listed. "Pure white in color, bearded. Good layers of greenish blue eggs. Leg color can vary in this breed. Mixing of two show strains has resulted in some interesting variation. We do not recommend showing these as some may not be what the APA Standard requires." Sand Hill also has them listed under extra-large egg layers. Has anyone ordered these? I would be interested in what the 'interesting variations' are, and if if they truly are extra-large egg layers.
