I got my eggs from James Meeks in Cleveland (he is know for his Meeks Line Blue & Splash Langshan), I bought an incubator from him and he gave me 18 various eggs from his different breeds. But BYCer - oldfort_mailman (Chris) also in Cleveland, also has breeds SS. He works with James with his Langshan project. If you want I can PM you both their phone #'s. Both super nice guys and very reputable breeders. Matter fact, James is VERY strict about his biosecurity. Neither would mind you calling them at all.
As for me, these are my first 3 SS. I didn't set out wanting to work with or breed these but just happened to be some that ended up hatching. Not ready to let them go yet, but we'll see, I would like a hen or two.
