Unless you want organic, try this soy free layer feed.
Best way to figure out for yourself is to try a soy free feed & see if you feel the same!
About 10 years ago I started getting sick to my stomach after eating eggs. I could eat a little, like in cake, in breading, etc. Turned out to just be the yolk, I could eat egg whites. Tried duck eggs, and they don't bother me at all, so now we keep ducks. I recommend duck eggs, I can't tell any difference. People who think that there is a difference don't notice if you don't tell them.
