If it was a typical Brahma National, (at least the ones I have attended in Columbus Ohio over the years), there will be a good number of quality Brahmas in the sale pens. Some times birds in the show can be purchased as well. I suspect the Avian Influenza scare may keep some breeders, or at least some of their birds home.
Like always, it is best to make contact with breeders prior to the show. Let them know what you are looking for, and make arrangements to pick up at show. If you are going in cold, get there as early as you possibly can, the good birds usually go fast. Come strolling in Saturday afternoon and the birds have already been picked over pretty good.
I doubt I make it over. I have gotten spoiled here in Ohio with the quality shows we have nearby and never really have traveled out of state for shows, the crossroads show in Indianapolis a few years back being an exception.
if you do decide to go, please let us know, maybe i could get some eggs if you do?
