Wild duckling very frightened :(

[Kanrayhen24]

Hi everyone. So a couple of days ago I had to take my dog into the vet, when someone came in with a wild duckling that had been separated from it's mother. I have indian runner ducks at home and have raised 6 ducks from hatching so I have experience raising ducks but, this duckling is so frightened and I'm not sure it's eating or drinking but I have her in a box with woodchips and a heat plate plus gamebird meat crumble and water. I'm not even sure what type of duck she is? Any ideas on how I can get her to calm down a bit?

Is there a wildlife rehab in the area?
Keep it in a dim, quiet place until you find a rehabber.
