Wow, you guys have a lot of rules and regulations regarding egg sales, etc.! ... As farm as I know, our local farmers markets are open freely, no fees, you just come and sell after registering with them. At the closest one it is free, just provide your own tent and table, I'm not sure of the Stirling one, but I'm certain it's the same.
We're going in the spring taking eggs, and hobby farm products. The "Comfort Country," is a huge thing here, it's their marketing plan for the three major communities, Madoc, Marmora, Tweed, and Stirling, and it's all about making the farming life available to the regular joe, and giving the rest of Ontario a good look at Hastings County. We're still a very rural/farming area, and the area is making sure it is going to stay that way
I don't believe there are any regulations that affect small producers regarding taking eggs to market, Meat yes... you have to be government approved or something, but I don't believe you need to be with eggs, though I'm not entirely sure!
