I've planned a year for my ducks, We've worked so hard to make it a perfect place for our flock. We are finally getting 4 eggs a day. Enough for our family and some to give away. Now all of a sudden, I get terrible stomach pain after eating duck eggs. My son also complains of stomach pain.) What gives? Could we have developed an allergy? Are they just to rich for our systems to handle? If I change the feed, will it change the eggs? Has anyone else had this happen? I'm so disapointed I could cry.
