A few random thoughts:
I saw a white Chantecler in the exhibit hall. I didn't see anyone selling any Chanteclers, though. (There were many other breeds being shown that were not for sale, I mention the Chantecler because that is a breed I would have been interested in buying.)
It seemed that there were 3-4 times (maybe more) bantams than standard size chickens.
There was a standard Barred Plymouth Rock cockerel and a standard Rhode Island Red cockerel that were impressive in size, at least from a visual point of view. I wonder how much they weighed. If either owner is reading this and knows, I hope they will share.
I had the mistaken impression that fowl would be the focus of the auction. Maybe I missed the real auction, but all I saw being auctioned was flea market type items.
I was at a goat show at the Windsor fairgrounds a couple of years ago, presumably there was a concurrent chicken show then, too. But, I completely missed the poultry exhibit hall when I went to the goat show. Perhaps more signage or cross advertising would be beneficial.
