Correct me if I'm wrong, but the OP doesn't know what type of duckling it is and as we don't have pics and as the duckling is still very young, any attempt to determine its type could be completely wrong at this point. And, as was stated earlier, it's not normal behavior for a wild duckling to go towards humans in the fashion described by the OP, it could very easily be a drop off by someone who found out that ducklings are a lot of work, or couldn't keep it, or some other reason we obviously can only speculate about.
Until there is confirmation that it is indeed a mallard, any legal issues are moot.
While I do agree that it is best to inform the OP about the laws, regulations, and potential ramifications, there is no point getting noses out of joint until there is proof that something illegal has or is taking place.
