Yes, you can pickle them. They also can be pasteurized in shell. That's not a technique that we've looked at just yet.
With the volume of eggs they'll be going through with their hot meal program, I suspect that as they're hard-cooked, moved out, and consumed, we'll be looking at a matter of storage for maybe a week or so, rather than months. We will have the kind of facility that's part of our farm and has some cold storage capacity, so we should be okay there.
