Hi, We've had ducks since summer now, and they've been laying like crazy. That would be a dream come true if we could eat them. My parents and I have all recently developed a strong intolerance of our duck eggs. Eating just a bite causes pains, vomiting, light-headedness, etc. for the rest of the day. Our friend volunteered to take some off of our hands after we told her we were apparently allergic to them. Sure enough, she calls the next day to tell us she is horribly ill from the eggs. Is this a crazy coincidence, or is there something wrong with our duck eggs? We feed our chickens and ducks the same feed (the chicken eggs are fine to eat) and the ducks seem perfectly healthy. We really hate tossing eggs but we can't give them away either for fear of them causing more reactions. Thanks in advance for any advice.
