Chupps has a 10 acre site that is often filled with rows and rows of about everything you can imagine for sale. I don't know how many auctioneers they have going at any one time, but it's definitely several. They just go down the rows and auction things off.
The animal sale is in an outdoor covered arena sort of thing. If you bring anything to sell, come EARLY. I know someone who started out very early from his home and got there at 8 a.m. and they wouldn't take them because he was there too late. When you bring your animals, you just set them out in rows and stay with them until they come by, take your information, number what you've brought and give you something to claim your money with. You don't have to stay. If you want to leave, they'll send you a check Monday. Very few animals are in decent cages; nearly all are like Q said. You can't really get a good look at a lot of them; especially those in cardboard boxes with wire tops. When I take birds, I label them with quite a bit of specific information since they can't really be seen well. I include that my flock is NPIP Certified. I started out with better boxes with side "windows," but now do the cardboard boxes with wire tops. I don't take my best birds, though they're better than most hatchery birds, and usually get anywhere from $3.50 a bird to an occasional $15. I've never stayed for the auction, because when I've been there it has been COLD.
Baby chicks often go for less, and they're often crowded in cardboard boxes that you can't see into without opening them.
They usually have quite a variety of animals, from tiny baby chicks, to lots of baby parakeets, guinea fowl, peafowl, ducks, geese, little baby potbellied pigs, to full grown goats. I'm sure they have a lot of other animals from time to time.
Another reason to go early is to find a decent parking place. The traffic gets very bad in both directions.
They have a decent concession stand, and have stands for all kinds of produce, as well as some very commercial stands; Sprint, for example.
