You'll have to get them from a breeder or a couple of hatcheries, Sandhill Preservation is one. Most don't have them, but there are several folks here who do.
I have a trio of them and will start hatching in March hopefully. If the fertility improves I could let you know if you are interested in hatching eggs.
I have some for sale. Pm me for my phone #. I also have several blacks from top lines. For bantams contact jmhappycowboy here on BYC He has some of the best.
