I gotta throw this in: when my dad, who was an avid duck hunter, passed away, we defrosted the freezer in his garage (the glacier). Found all manner of mummified birds in it, including one teal with a tag from `86!! Of course, the old man had lost his sense of smell, and pretty much his sense of taste, so he'd put something like that rancid, freezerburned bird in a crock pot and stew it. The smell alone kept the rats out of the house!!!
