Also - the salmonella fear connected to chickens. Many believe it is only transferred to the outside of an egg through the chicken's feces. This is incorrect. Many birds now carry salmonella within their bodies, thus, it can be found INSIDE the egg - which is why fully cooking eggs has become so important in these current times.
