I Pro-cured some eggs last Fall and vacuum packed them in pint jars, I noticed that most of the eggs on the outside layer of the jars still got freezer burned. The ones on the inside looked and felt fine month later when I thawed them out.
This year I'm going to borax them, keep a bunch of borax in the jars, and see if that helps.
