Make sure it knows where the food and water are. It won't absolutely need to eat or drink until the third day, but it should know where that stuff is. It may just need a bit of time to recover from hatching. Make sure it's warm enough - not too hot or cold and keep an eye on it.
Well, it's able to at least sit up some, so that's a good sign. Sometimes, they don't make it through the hatching process, though. However, just make sure she has what she needs and give her some time. Good luck!
