Well here's my experience with them. I go down to help set up at about 6 am and there are cars lined up halfway around the block already waiting to get in. The earlier ones in the year usually get 200-300 people through the gate. Later on in the spring its sometimes closer to 500. If you want anything decent, you get there between 7-8 am. Most people are sold out or are packing up by about 9 am. At our BCPPA swaps we have a huge heated building, bathrooms, a lunchstand, and a raffle. Some of the other ones are simply a get together in a parking lot. If you come to sell, bring your birds/animals in cages so people can actually see them. If you stuff them in a dog kennel, people tend to walk by. Setting up a table and lawn chair never hurts either. As a seller, bring boxes, crates, etc to stick whatever you buy in. **If you have poultry to sell, make sure to have the appropriate health tests done beforehand.
What you may see can be soo variable depending on who shows up. Usually the place is filled with ducks, geese, chickens, pigeons, rabbits, and the like. You see alot of people with the small house pets such as guinea pigs, degus, canaries, finches, cockatiels, doves. You get some bringing goats, lambs, llamas, mini horses, pot belly pigs, puppies. It depends on the people, but sometimes peafowl, pheasants, quail, turkeys, exotic ducks, swans. You also get the equipment....welcome to bring anything used or new...incubators, feeders, waterers, nest boxes, carriers, etc. You can pick up some really good deals and also come home with a load of crap too. Last year I wish I had a flat bed trailer along. Someone brought those huge hanging rabbit breeder cages complete with feeder and waterers and was selling them for $5 per section. I was also picking up brand new wooden 3/4 stall nest boxes for $10 each too. The Asians snatch up most of the really cheap birds as they are carting them in from the parking lot.
