I'll have plenty of them here pretty soon. They are sort of rare. At Ohio Nationals there are only a handful every year. They are a medium class goose therefore should be smaller than embden and africans. Also, they should have a single keel instead of a double like the pilgrams.
I don't know how rare they actually are, but I know that Superior Farms has them. They sell goslings there. If you want the website address, pm me and I will get it to you.
