Frozen doesn't stay good as long either.Lime water preservation is also called "water glassing". There are a bunch of threads on it if you are interested. However, it doesn't really sound like you are concerned with preserving eggs. Freezing is also a good solution, but takes freezer space.
My biggest concern with water glassing is the heat where I am. We have a couple of months of intense heat and we don't run the ac at night...we don't set it lower then 80 during the day either. I worry the heat will ruin the eggs.
I'll have to look for those threads. No time like now to try it
