I'm not getting very many eggs at the moment - about 18 a day. Of course that's more than my family can eat, so a few months ago my mother put an add up on her Facebook page and got so many replies from her friends that I had to deny some people! I've got a lot of chicks and pullets at the moment so will have a lot more eggs to sell this year. I sell for $2.50 for half a dozen, $4.50 for a dozen, and $20 for five dozen. I've noticed that 'free-range' eggs in the supermarket tend to be about $4.99 a dozen.
I used to sell at a community market once a month down in town but found it was too irregular - every four weeks - and it was getting difficult to take eggs that far. Most of the Farmer's Markets around where I live have become quite expensive to sell at - I got 15 pages of paperwork to fill out when I enquired about having a stall at one of them! Not to mention the price of having a stall! Besides, lots of people sell eggs at them as a side to whatever else their main product is, often for cheaper prices than me. So markets aren't a viable option for me. I also don't think having a sign out the front would work... I live on such a remote, inaccessible, long road, that the only people who drive down it are the ones who live here, and most of them have chooks themselves. There are a couple of people in the area who sell eggs from little shelf-house-thingies at the ends of their driveways, but I'm not sure how much business they do!
Apart from that, if we get too many eggs, I can usually find something to do with them. We don't often get too many chicken eggs, but we find that duck eggs are much harder to sell (are people afraid of the unknown?) so we often have too many of them. Being summer, we've been going to a lot of barbeques - a good place to use up eggs in curried egg or egg salad, not to mention making it for consumption at home. My mother recently pickled thousands of duck eggs, too (well, maybe not quite thousands...).
Just a comment about the freezing of the eggs - I tried that once and they cracked. What's your trick?
