I have a number of dead wild birds in my freezer. You see, I'm a wildlife rehabber and we use the ones that don't make it in classes, so into the freezer they go! Better not to open the plastic bags in my freezer.
At one point I had a juvenile wild turkey who had been euthanized in my freezer, and he took up most of the freezer space!
(This is odd to me because I'm a vegetarian and don't keep meat or anything in the fridge/freezer.)
A bottle of penicillin.....I think that is the strangest thing, which isn't so strange for peeps on here.
Now my Grandmother, on the other hand, kept a frozen mink to show everyone after she found it dead close to one of the out buildings. I got tired of shuffling the thing around the freezer over the years.
