Temple, Many folks have thinned down to breeders at this point. I'd get on someone's wait list for chicks or eggs for the spring. Another option is to get someone to sell you a male after they've finished hatching in the spring. Your hatches might be late but at least you won't miss a whole season. Birds are going to be scarce until folks have filled their own brooders in the spring. Many bantam breeders start hatching in March/April Folks will be wanting stock after the first of the year and wonder why there are none to be found. Plan ahead now and take advantage of those who are offering chicks for the spring.
But your search for black bantams brings up point. It seems that bantams are falling out of popularity through out the country. Blue Wheatens almost went by the wayside until thankfully a few folks picked up this baton. Its hard to believe that Blacks are not that available now. Keep looking and keep some of those other bantams going, pass them on to some others. And raise a bunch of the whites too. Folks are trying to find sources for this great variety. If we have blacks and whites, we can reinforce many of the other colors as needed.
