What about salmonella?
I recommend that you cook your eggs before dehydrating. . Do not use oil, if you use oil, the oil will go rancid while drying and in storage.
When you're ready to rehydrate for cooking, add water at about a 1:1 ratio. Then use them like you would fresh eggs.
When you preserve your eggs this way, you increase the shelf life to several months. It's a good way to save them if you have chickens or bought a bunch on sale. It's just another great use for a home food dehydrator.
