integrating an imprinted duckling

I have an 8-day old duckling that seems to be imprinted on humans (we incubated eggs, she was a late hatcher). We live on a farm that has a flock of young ducklings (about 2 weeds old) Integration is not going well, do you have any advice? She seems so young - is it possible for her to discover that she can be a duck? There are also 6 adult ducks who keep to themselves (her parents)
