I will sometimes freeze them fresh if I don't have cure on hand. I think they stay good frozen for a while longer than in the fridge. They seem to deteriorate rapidly in the refrigerator, I would say 3 days and they are well on there way to being garbage.

When I freeze them fresh I wrap them in a paper towel and make little "egg burritos" and vac seal them. Key is getting all the water and air out before you freeze.
