Indian Runner duckling - is this a tail curl?

[missmaqs]

Hey does my duckling look like a boy? Hoping she's a girl because she's loving my flock, but if she's a boy I am concerned about mating. She's in between 1 and 2 months so can't tell by the quack.
Very new at ducks, maybe I just need to be patient

Not a tail curl - too early.
