Ke-Peg is a product that as far as I know, is just waterglass, which is available at your pharmacy. (I think it's a liquid form of water and silica, which is the mineral of which glass is made...stop me if you've heard this one before.) Anyway, you can supposedly also rub KY Jelly on the eggs to preserve them, as I have heard that it is the same stuff just different form. You can also use petroleum jelly (vaseline). I think this is to preserve the eggs in case of maximum storage requirements: i.e. hiding out in fallout shelters for a long time, etc.(posted 9640 days ago)You can also dehydrate eggs, freeze eggs, and pickle them if you are interested in storing them without the shell. I prefer to store mine in my chickens, and harvest them daily. The extras that I don't keep for a few weeks, or know I won't be keeping, I sell to some local folk, or give away to friends.
At any rate, I have seen advertising for KePeg (keep egg, get it?) and while I support alternative companies that are just trying to make an honest buck, I think there's also a generic version available. Just my $.02 FWIW.
