I've put an ad in the local paper, and also on a local internet service. No one is responging to duck eggs. I've put them in for $2.50 a dz and $4.00 for 2 dz. My refrigerator's full. How long can I keep these eggs? Also, any suggestions on selling them. I don't have a car. I rent a car one day a month to do all my shopping and feed. It was give up my animals or the car. So, I'm grounded. Any suggestions on selling the eggs, or do I give them to a church?
