Could be the OP's fridge is just set a bit lower than other
refrigerators on Earth, or opened less, or ...

We keep our refrigerators pretty cool, and five days sounds about right
to me for a solidly frozen turkey of any size. She might still find
some ice crystals in the cavity even then because of the giblets being
jammed in there, but hopefully nothing that a rinse in cold water won't
fix.

Why does yours take longer? Some sort of special bird, never seen in any
other supermarket on earth?
