Ever heard of someone allergic to store eggs but not farm fresh chicken eggs? I've been with my wife for 7 years now and her mother has always avoided eggs saying it makes her sick, but in the last year she has started eating my fresh eggs and they don't bother her. I wonder what that could be? I would think a chicken egg is a chicken egg, I have heard that people with egg allergies can usually eat duck eggs but this is obviously not that situation.
