If you are going in to a camp and then staying at that camp and not moving camp daily, here is another option. My dad came up with this idea many years ago. Use a size of bottle that will hold the number of eggs you want to take. Carefully break the eggs open into the bottle and throw out the shells. You will need to fill the bottle to the top with eggs. Once the bottle is full the eggs cant easily shift around and stay relatively intact with very little if any mixing. Come time to use the eggs they pour out of the bottle one by one. Once out of the shell like this the shelf life is rather short and you will want to use them up in a couple days. Also once you have used some eggs out of the bottle then they wont transport so well since there is now room in the bottle for mixing and sloshing. For a stationary camp, this method works surprisingly well.
