I posted this in another thread, thought it would go well in here. I am allergic to soy (and gluten), and thought that I was allergic to eggs. Through some random internet searching, I came across an article (linked below) about soy proteins being found in eggs. Additional research allowed me to find a local farmer that advertised soy-free eggs. Half a dozen eggs later, I had my own chicks, and they were on a soy free diet. Regarding the soy in eggs, this is a good/short reference that I keep handy: http://etd.ohiolink.edu/view.cgi/Vargas Galdos Dante Miguel Marcial.pdf?osu1236706764 The study was done to show the benefits of soy in a chickens diet. Not only does the soy protein end up in the egg, itself, but it also ends up in the meat of the chicken. So, depending on your level of allergy to soy, you may or may not react to commercial eggs or chicken. On top of that, if your allergy is not as severe as that of others, you may inadvertently ingest soy on a regular basis, which over a long period, could have cumulative effects on your health. Using that article as a starting point for myself, I've done quite a bit of searching to find answers about the same for gluten. So far, as I have found, the gluten proteins are broken down, and do not have an impact on the eggs/chicken (or those that eat them). For myself, I found a local farm that advertised free-range/soy-free eggs, and I gave them a shot. I can tell you that I do not have a reaction to those eggs, but do have a reaction to commercial (store-bought) eggs. I even have reactions to products that contain egg in them. When I started doing all the research, early this year, I made up my mind to get my own chickens if it turned out I could still eat eggs. As a vegetarian, the eggs are a good source of protein, and if I could control what the chickens eat, then I could have a better grasp on actually controlling what I eat! With regard to organic, that's a personal preference of mine, most of what I eat is organic. I feel like I'll actually be eating organic eggs if I can actually feed them organic food. It just so happens that the company I found that sells the soy-free feed makes it with organic ingredients.
