Store ought eggs are ONLY different in that the go from chicken to warehouse to store... Which means that nearly all store bought eggs are
1) significantly older (usually at least 1-2 months older)
2) infected with salmonella (from the time in the warehouse)
Chicken to Mouth is MUCH healthier and safer. In countries and regions where eggs go from small farms (less than 100 chickens) direct to store, there is almost no incidence if salmonella.
