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.
