Hi everyone, I am new to ducks and selling their eggs. I know that you can keep chicken eggs up to 5 months for eating; I ***-ume that duck eggs are the same? I will be putting an ad in my local craigslist to sell my duck eggs and I am wondering how old is too old and at what age of the eggs should I drop the price? I ***-ume that whatever my customers are willing to pay, right? I have given them away to my neighbors, but they are not repeat customers, they don't like them. My husband is allergic to them (he gets sick to his stomach) when he eats them. I am fine and love them. I have 11 ducks laying, yikes, I can only eat so many and bake with them. What is the going rate for duck eggs? per dozen. Thank you so much.
