Bourbon Reds aren't rare to us, but when I tell people I'm raising them, the vast majority have never heard to them, or any other heritage breed. And when you think of the millions upon millions of BBW being sold, they are comparatively quite rare.
But I don't know what's with the ALBC, either. Their numbers seemed really low to me when I noticed that numerous hatcheries carry them (as Steve pointed out), and saw how many people on this forum have them. Someone, I think it was Harp, said in another thread that they only count your numbers if you are a member of ALBC, in which case all their numbers may be way off.
