After reading Southernbelle and PC's posts I'm a little freaked about the thought of getting hatching eggs from others. Before I was aware that MG could spread by egg, I did a trade with a lady for a couple dozen hatching blue eggs (likely EEs). We met through Craigslist, so I know very little about her. Now I'm worried about getting eggs from someone I don't know. How prevalent is MG and how likely am I to have it spread by egg? What should I do?
