I've tried several times over the past couple of years to find a comprehensive listing, but I haven't had any luck. If you do a search on "poultry shows in California", you can find the sites for several different poultry clubs and their shows, but it seems that a comprehensive list doesn't exist. I've just spent some time on the internet and found a couple of big shows in my area to attend (Stockton and Fresno). If you find anything let me know!!!!
