Can germs get into a chicken egg?

The highest risk for contamination of an egg is Salmonella. The shell does protect against these organisms entering, but if it is cracked or highly contaminated it will not stop contamination. Washing the egg too much could also compromise the barrier causing contamination. If the egg is cooked properly, Salmonella contamination should not be a problem as the bacteria will be killed with sufficient heat.
