F/t rodent deterioration

So I remember a snakebytestv episode saying rodents can remain frozen for 6 months to a year before deteriorating is this true? I've been trying to locate the episode to reassure myself

I have some in my chest freezer that are going on 7 months and they still look good, & I'm quite sure they'll be good for a few more.

Usually a year is safe as long as Rey are packaged well. I have some that got freezer burnt pretty quick but others that are pushing 9 months. You should be more than safe up to a year if not freezer burnt.
