A hen’s egg contains a small air pocket just inside the shell at the broad end, the purpose of which is to let the chick breathe while pecking its way out when it hatches.
Because the shells are porous and permeable to gases, outside air can diffuse in and exchange with the air inside. Over time, the contents shrink away from the shell, more air comes in to fill the space and the air pocket grows larger. In this case, it moved from the end to the side as well.
Refrigerated raw shell eggs will keep without significant quality loss for about 4 to 5 weeks beyond the sell date or about 3 weeks after you bring them home.
A woman I worked with long ago called the way most people make egg salad "cackleberry mush". She said "true" egg salad is to slice eggs on bread, then spread mayo over them.
If you want to keep eggs even longer, oil the shell.
