I make refrigerator pickled eggs. They only last about 6 months, but are an easy way to have eggs to eat when the hens decide to molt!For those looking for ways to preserve food, one thing you may not have tried but likely have handy is eggs. I always save some eggs in the spring for use over the winter when the girls mostly or fully stop laying.
There are a number of ways to preserve eggs, but the three I think are best are freeze drying (very good but requires expensive equipment), freezing (works but uses valuable freezer space) or water-glassing (cheap, requires no power, but has ~10% failure rate). I've been doing water-glassing for a number of years now.
Here is the master thread on water-glassing:
