If you mean the weekly auction in Springville, that's in western new york, about 40 miles south of Buffalo. Which is really far from Onchiota.
But since I'm kinda local, here's the scoop on the Springville auction. It happens every Wednesday, all year. It's an all-purpose farm auction - people bring all kinds of stuff. There are vendors with antiques, fruit and vegetables, cheese, jewelry, the usual flea market fare. The livestock part is run separately, and they get poultry, pigs, goats, etc. If you're troubled by seeing animals sitting around in small boxes, don't go. Some people improvise their crates and don't do a very good job. The kinds of chickens that come through there are usually not "fancy" breeds - mostly standards like RIR or rocks - the kinds you'd find on a farm.
I went once or twice many years ago, but my dad's a regular. He's always bringing home random stuff - he just can't resist old electronics.
