the badger would win
I would say a wolverine but maybe a badger could win every so often.
A badger would probably win. Badgers are generally larger and not as good natured as otters.
Normally a badger would win a fight with a squirrel. The reason to as of why is because with a badgers brains and brawn opposed to a squirrels brawn, it would outthink the squirrel easily.
Probably the badger because its stronger than the duck.
