I'm assuming you're talking about a syrian & I only really know about dwarfs but generally I think it's better to give too much rather than too little at least to begin with then you can figure out how much they are eating vs stashing when you do a cage clean & get a better idea of what's needed.
Dragging the food bowl sounds like she just wants it closer to her nest, either feeling a bit insecure or maybe just lazy lol! quicker & easier to eat or stash that way!
Not sure about spitting food out, maybe she didn't feel she had anywhere safe to stash it right then or she was more interested in what you were doing.... just guessin!
