how long do store bought eggs stay fresh
Retired in 2005, breeding Araucana chickens. Most store bought eggs have a best before date on the carton but 30 days is usual. You do not need to throw out eggs older than that, just do a float test. Put the eggs in a bowl of water and throw away any that float to the surface, boil up the rest and use for lunches etc. 3 people found this useful.
