Do you store eggs point up or down?
Keep eggs facing upside-down in the carton.
That's because there's a naturally occurring air bubble inside each egg's rounded side, which helps keep the yolk more centered inside the egg and, in turn, will help your eggs stay fresh longer.
Eggs should not be stored on the refrigerator door, but in the main body of the refrigerator to ensure that they keep a consistent and cool temperature. Leftover raw egg whites and yolks should be put in airtight containers and stored in the refrigerator immediately.
If you hold the egg fat end down, that air pocket has a tendency to rise not completely through the egg, but enough to reach the yolk. By storing eggs fat-end up, the pocket of air stays away from the yolk, and the egg stays fresh longer.
Eggs exit from the ovipositor in a semi plastic condition and tend to hang pear shaped until the shell has solidified after which a quick squeeze sends them to join their fellows. So blunt end first.
Best practice is to store eggs in the fridge; that way the temperature is always at a constant and your eggs will be fresher!
As the egg freezes, the egg yolk and white expand, and can crack the egg. If they don't sit for too long, or if the weather is not terribly cold, they don't crack; however, if they get too cold, or stay frozen for long enough, they will develop cracks in the shell, and sometimes even the inner membrane is affected.
Eggs may be refrigerated three to five weeks from the day they are placed in the refrigerator. The "Sell-By" date will usually expire during that length of time, but the eggs will be perfectly safe to use. Always purchase eggs before the "Sell-By" or EXP (expiration) date on the carton.
Experts believe that eggs are best stored at room temperature. Storing eggs in too cold a temperature, i.e. in the refrigerator can make them inedible. Keeping eggs in the fridge cause the growth of bacteria on the shells and this turn and enter the insides of the eggs, in turn making them inedible.
But storing eggs upside down helps them last longer by preventing the air inside an egg's shell from coming into contact with the yolks, explains egg farmer Lisa Steele, a fifth-generation chicken keeper from Maine and the author of the blog and the Fresh Eggs Daily Cookbook.
If you want to preserve them for longer than the recommended 4–5 weeks in the fridge, you can crack them into a freezer-safe container and keep them frozen for a year or more. Eggs can be stored in the freezer indefinitely, but their quality will start to decline after a certain point.
Which end of the egg is the bottom?
Eggs should be stored pointed end down to keep the yolk centered and keep any bacteria as far as possible from the yolk, which is far more likely to be contaminated by any bacteria that enters the egg than the non-bacteria friendly white.

All eggs contain an air pocket at the base (the wide, rather than the pointed, end). When this air pocket is heated, it expands. If it is heated too quickly, it more like explodes, cracking the shell.
And not in the pointy end so when we're storing. It we want to put the pointy end down.
