You can’t sell farm gate as the regulations here call it? I don’t think you can here if you are a registered producer of something else but you can sell duck eggs because they are not regulated. But there is a fresh egg sign fairly regularly in my area. I let my daughter collect $3.00 from the neighbor we sell to but give away to my one adult child and her roommates and a friend who is kind to us often bread ,child care,a jar of her fresh jam ( which has been going on much longer than I have had eggs). And yes to pound cake or custard but I am going to get fat.People I trade with know our eggs are unwashed and not refrigerated.
I wish I could sell some extras. The guy who set up our internet wanted to buy 2 dozen a week rather than go to the Indian reservation, but we aren't allowed to sell from our back yard so I said no.
