I'm out of your area, so don't know what's going on there. Sorry
To find shows, you get a subscription the The Poultry Press. It has shows listed. It's a small newspaper, 12 issues a year. News about shows, nice photos of winning birds, ads for birds for sale, and a few articles about how to raise show poultry. Cost isn't too bad, if you enjoy poultry.
Also, you can go on-line and download Exhibition Poultry. It's a E-magazine, free, and I've never had any problems result from downloading it. Upcoming shows are listed.
