What is the shelf life of farm fresh eggs as opposed to store bought eggs?

Farm eggs last longer than store bought because you eliminate the packing and store from the picture.I would say a month,I raise chickens and have kept them longer,but to be safe a month is good.

You can fill your kitchen sink half full of water,then place the eggs down in the water.If the egg floats, it is not good.
Eggs from a farm are richer than most store bought eggs.The yolk is usually deep orange,and extra yummy.

I think they treat store bought eggs to make them last longer... Feed chickens dye to make yokes yellow...
