A lot depends on your area. I have people asking to buy my duck eggs, but I only offer table eggs when my hens are separated from my males so certain times of the year unless it's family. I keep my ducks very tidy, they have a minimum of 20sq ft per bird at night (sometimes more depending on pen) and spend their day foraging. People will pay more knowing that they're buying eggs from well kept, healthy and happy ducks living their best duck lives lol I don't ask for money, but anywhere from $5-$10 for a half dozen of table eggs is what I'm given. Something else to think about, but I have personally talked to people who have admitted to trying to hatch out table eggs from breeders especially those with rare breed assortments trying to get them at bottom dollar prices. Since I have a rare breed and have spent a lot of time and money putting together my flock and selectively breeding absolutely no fertile eggs leave my property. I also have my mixed breed layer project that I was working on and I don't want people trying to hatch those either.
