Pointy end down

Eggs have a natural air sac in their blunt end, where an incubating chick receives its oxygen for survival <3 Eggs are also always laid blunt end down, so that they have the most surface area to land on and cushion themselves. When an egg is stored pointy end up, with the air sac at the bottom, that sac will slowly rise and move towards the yolk, bringing any air and bacteria with it.  That will hasten not only the aging process of the egg, making it less fresh since keeping the yolk completely enclosed within the white protects the yolk from drying out, but also increase the likelihood that salmonella or other bacteria will reach the yolk more quickly and contaminate the egg. There is also a chance the air sac will rupture and contaminate the egg with any bacteria it contains. [fresh eggs daily.com]
