Not at all, I'm pasting it down below. They ducks free range all day and we give them veggie and fruit scraps.
I have celiac disease and I have food and environmental allergies, plus a close relative has an autoimmune disease and non-celiac gluten sensitivity (affected by gluten topically and internally), and I react poorly to eggs from chickens or ducks that ate gluten-containing grains. I also can't eat chicken meat (my personal preference is to avoid duck meat) if the chickens were fed gluten grains. There are plenty of folks who are quick to point out that there's no scientific evidence that gluten passes through into eggs or meat but more functional medicine doctors are realizing that for some reason, there are people (like me) who show physical reactions to one or both of those things if a bird's diet contained gluten. I've gone through years of a range of tests, including elimination diets, to determine the cause of my reactions and it's gluten. That's one of the biggest reasons why we started keeping a flock of ducks—we could control their diet, and I don't react to their eggs at all.
