Loopy Louey (Or Louise)

That silly duck was on his back again.  (I'm assuming a he for now)  I've decided to call it Loop Louey (or Louise if it turns out to be a hen).  I don't know what to do with this poor thing.  Every day it's on it's back.  I know it's been there for an extended time because the first thing it does is run to the water dish and drink.  I'm really worried that the poor little guy is going to get dehydrated one of these days.  What can I do?
