I went to the website and I can't find anything on how to get info about trying to get a seller space or even info on trying to get a bird in the show.
Am I just missing it or something?
No, you aren't missing anything. They'll update the website this Fall, when it gets closer to the show date, probably the end of September, early October. I'm fairly sure that seller cages are sold to exhibitors only. If you aren't showing I don't think they offer sales cages to outside individuals.
Maybe you can get answers on the sale cages so you don't have to prep birds for a show. But as I recall, that's the way it is. Sale cages for exhibitors only.
