Thanks. Unless I'm wrong about this, I've read that chicken's are given various diets depending on whether they are used for egg laying, or going to become someone's meal. Free range doesn't necessarily mean they aren't getting some grains in the supplemental feed. I'll be calling various company's to find an egg I can eat. I switched to grass fed beef a few weeks back, and I can definitely say I think it makes a difference in how I feel after a meal. I didn't think I was that sensitive, but I guess I am.
