I just wonder if there is any problem with selling eggs from our ducks? We only have a pair, but may be getting a couple more females this Spring. Our female has laid one to two eggs all winter. I ask as my husband developed a horrible reaction or allergy to duck eggs, and I can't even tolerate chicken eggs all the time, either. So I wondered what if that had happened to someone who had bought eggs from us? Is there any liability on our part?
