Eggs – How long can I keep eggs in the refrigerator

To keep eggs useful and healthy, what is the average time I can keep them in refrigerator? Can I freeze, and re-use them after melting, or will they be useless or not healthy to eat?

Back in the 70's, the folks at Mother Earth News performed an egg storage experiment. They stored them in a variety of ways, both refrigerated and unrefrigerated, to see how long they could keep. They concluded that unwashed eggs (aka, "hen fruit" or "cackleberries") stored in a sealed container, and kept at 35° to 40°F, were still perfectly edible after seven months:

(1) Unwashed, fertile homestead eggs seem to store much better than washed, unfertile agribiz eggs. Why? Probably for the simple reason that they're unwashed ... and not because they're fertile. Hen fruit, as it comes from the chicken, is coated with a light layer of a natural sealing agent called "bloom". And, while a good wash may make a batch of eggs look more attractive, it also removes this natural protective coating ... leaving the eggs more subject to aging and attack by the air and bacteria in the air.

(2) The very best way we've found to stash eggs away for long-term storage is in a sealed container at a temperature of 35° to 40°F. Their whites may become somewhat runny looking over a period of time, but even after seven months—the cackleberries stored in this manner smell good, taste good, have a good texture, and—in short—seem "almost fresh".

Update 2011-02-19: This discussion inspired me to do some experimentation of my own. We keep chickens, so I plucked two eggs on October 2, 2010 and put them in the refrigerator. I just pulled them out today. Here's a picture of one of them next to a fresh egg.

One of these eggs was laid yesterday and the other was laid 140 days (4 months 17 days) ago. Can you guess which is which?

Update 2011-06-05: I completed my eggsperiment today by cracking open two more eggs that I have had in the refrigerator since October 21, 2010. Here they are:

There was no trace of odor, but the whites were definitely lacking in firmness. I scrambled them. They didn't make for very fluffy scramblers due to the watery whites, but they tasted fine. So, I can confirm the findings of the Mother Earth News experiment. Fresh, unwashed eggs stored in the refrigerator were perfectly edible after 7 months 15 days (227 days)!
