Hello Annie,
People never believe me when I tell them that the eggs they are buying are at least 3 months old. I was maybe EGG-aggerating at six months - but you can keep them for seven - your own that is

This is a link that I have found saying 6 months.
Fresh Eggs Shelf Life, eggs shelf life is 6 months from the date of production ... Brown Shell Hen Egg Export, brown shell hen egg red onion and potato from ...

So I am only quoting this.
The link below gives you the statement below it:-
http://wiki.answers.com/Q/How_long_will_fresh_chicken_eggs_keep_in_the_refrigeratorLength of Time Chicken Eggs are Good Farmers have 30 days from the day an egg is laid to get it to stores. Then, the stores have another 30 days to sell the eggs. The FDA recommends a maximum of 5 weeks in your refrigerator before you discard your eggs. What does this all boil down to? On April 1st, you could be eating an egg for breakfast laid on Christmas. *Someone who talked with an egg farmer was told from the day it was laid, the egg has 30 days. I assume that means until the sale date, but that was not made clear. *Even if that is true, keep in mind that farmers generally get their eggs to stores within a week, and both the "pack date" and "sell by" date are stamped onto the carton. The numbers run from 1-365 depending on the day of the year. Lastly, there is a big difference in taste between farm fresh eggs and one week old eggs. If you want the freshest eggs, you can buy from a local farmer. *
Therefore 30 days plus 30 days, plus five weeks in your refrigerator and these eggs are THIRTEEN weeks old already.
OUR PLUS SIDE -HAVING EXPENSIVE HENS IS:You can safely store home reared UNWASHED, fertile hen eggs for up to seven months at room temperature in boxes for your own use, and they will still taste fresh.
Hens put a bloom on the egg shell when it is laid that protects the egg from water and air pollution so the worst thing you can do is wash it.
Once washed you shorten the life of the egg considerably.
There are special stones available to clean eggs, that are used in all farms that supply Tesco's, and other large egg producers providing eggs for supermarkets use them too.
Many Supermarket eggs smell
after you have cooked them, ie the pan and plates smell - this is because your eggs were at least three months old when you purchased them

Scary but true
