what do i need to do

I don't give mine anything but food, and they do just fine. All that other stuff wont hurt them, but not necessary.
Get her to the vet ASAP they can give her a shot that will cause her to make milk.
I had one do that years ago, might be something wrong with her. But for sure give her all she can eat.
Ive got a female that I have to switch feeds when she has pups, for some reason she wont touch her regular food til about time to wean.
Might have to bottle feed with goat milk replacer just make sure and read the back, get the highest % of fat and protein, cause their not all the same.
You can also get 1 tub of plain yogurt, 1 can of condensed milk/creamer, 2 tbl spoon of mayonnaise, and 2 eggs. Mix well, has worked well.
