I just received a package today from Big Cheese with 50 Large Adults and 50 fuzzies. They are all frozen together into blocks and I'm not sure how to safely separate them and prepare for storage. I was thinking of defrosting them enough to break apart from the clump and then packaging them individually into little ziplocks. Would that work or do I need to individually vacuum seal? This is a 6 month supply in a normal household freezer.
