It can take them a full day to get their act together. I would make sure it is in a warm brooder and let it rest and sleep and not worry about it until Day 2 is well in progress. It can take geese and ducks 2 or 3 days to get their webbed feet flat and moving in properly.
What both posters have told you. Leaving it in the bator gives it a chance to get its sea legs underneath it, rest and fluff out. They are not active, active for a day or so just like any newborn animal, wobbly on their feet for quite awhile.
