Is there a specific reason like a breed, for the ducks that have upright tails? I'm just curious i have two ducks, That have upright tails, And the body characteristics you would normally see for the bathtub rubber duck. However they are to big to be call ducks, I know they are mixed ducks. They are so cute and adorable, but i can't find any species of duck that actually holds its tail upright normally, without any agitation. They are 4 months old, shown in other posts. About other things, They are Two very different looks. But the same body structure. As you can tell with the drake (Geisha) His drake feathers actually push back into his back. Due to the upright of his tail. Both have barred wings.
