I just talked to a guy from this new sale and he said it is run by the WigWam people. The reason it is the same day as the Scottsville one is because they have something going on the other Saturdays of every month. (horse sales, etc) As I figured, he didn't know about the Scottsville one. He said they are charging $10 for setup fee.
As for me..I think I will stick with Scottsville, (at least for now). I have taken birds to the Horse Cave Flea Market before and I found people not as willing to pay much for a bird. At Scottsville I don't have any problems getting my price on anything.
I think too that it has the potential of ending up like the Sano auction..cheap, sick birds. I have had several of my customers complain that they bought birds at Sano and within a week they died. I know that my experience there was that people wanted whatever they could get for next to nothing. I went twice and that was enough for me.
