Just wondering how long I can keep frozen mice in the freezer before they go "bad"?
With all frozen food it will last 6 months before it starts to lose nutritional value. By 1 year it is still edible but not very nutritous. After 1 1/2 it's better to toss it than keep it. This includes salted foods.
If you look up 'nutritional chart for falconers' there is a chart out there that will give the nutritional value of some food (including pinkies to lrg rats) and how it depreciates over time. I have it printed out, but i don't remember where i got it.
