Good luck with that.... and you find any, let me know. Here's one breeder of them in the United States, the only one I've ever found. You can get them from Italy from a fellow named Marc King, but I don't even want to think about the cost of impoting them.
Maybe try the Rare Chicken Breeds 2 Yahoo group??
Toni, PattiAnn, Jacen are all personal friends of mine and should be able to help you out. Maybe not now, but when spring comes they should start laying lots more. Good luck!!!
