I sell my free-range eggs at our local farmer's market for $4.00 for large, $4.25 for extra large and $4.50 for jumbo. Our hens are free-range (we open the door and they have access to the whole farm). I don't bring anything that is more than 10 days old. I also sell at church. I usually have about 5-6 doz. to sell each week, and I sell them all. When the market closes in October, my prices may go down for the winter, as I don't anticipate reduced egg production (we use a light), and I may end up with a fridge full of eggs again.
I'm starting to run low on cartons. If I have to start buying them, I'm going to have to increase my egg prices. I already have a stall at the market to sell other things, so I don't factor that cost into the cost of my eggs.
Roadside signs in our neighbourhood advertise prices from $2.50 and up, but I always sell all my eggs at the market. One factor is convenience: people don't want to have to pull into a roadside stand or go up to a farmer's house to get their eggs. Freshness and free-range could also be a factor: at the market people can ask me about my chickens and how I raise them, and I have an opportunity to tell them when the eggs were laid. Each carton is labled with the size, price and date of harvest. Our regional health board requires that I lable the cartons, wash the eggs and keep them chilled during transport and at the market.
