For long term storage of the egg I totally agree with disinfecting it in some way. And it may even be a good idea with this little experiment I'm doing. Since my main reason for experimenting was for shipped eggs I reasoned that they are generally 1-3 days old when shipped and spend another 3 days in the mail. So I decided to stop the first experiment run at 1 week. I haven't simulated climate or movements, so I suspect at 1 week my eggs should be 100% viable.
I think climate and movements can play a part. The eggs will sweat a little moving between extreme weather conditions just based on temperature. Example is removing eggs from the fridge and sitting on the counter. They sweat.
(As a side note to this sweating issue and refrigeration, I have hatched neighbors eggs which were sitting high in their fridge and partially frozen. Strangely I hatched roughly 8 pullets and 1 roo from that, and the neighbor generally has a high percentage or roo chicks. Future sexing experiment?

The eggs were not meant for hatching, but I tried anyway.)
I'm hoping to do a running experiment, trying different things and seeing what happens. My first experiment was au naturel, 2nd would be disinfecting if there was a issue. Since I don't generally get dirty eggs I may not have any problems with bacteria entering the eggs at all. If I did have a problem I was going to use 91% isopropyl alcohol in a sprayer and just mist the eggs. My thought is it will evaporate rapidly and not add or subtract much water content from the eggs and they can be wrapped in plastic quicker than waiting on a water based antibacterial to evaporate. I have well water and have considered any type of cleaner which I do not have to add my water to, otherwise I would need to buy some distilled water for mixing concentrates.. I do have a concentrate aviary cleaner on hand called Pet Focus. It's wonderful stuff. It's safe to spray around the birds so could be safe for eggs if I reconstitute with distilled water. It kills a LOT of baddies.
1st run all I did for disinfecting was for myself. I washed my hands and used hand sanitizer. Eggs were gathered and placed in my shirt, while not sterile was clean. This experiment is still running.
I may try a 2nd run today, using alcohol spray, letting it evaporate and then bagging. It would be good if I can get another of those dirty pullet eggs. I want to see if trying to clean the egg would make it worse or better.
Thank you for joining in! The more the merrier and more ideas to check and double check and explore etc
