As long as she is drinking and eating dandelions and hay, then she will be ok I think.
You don't have to syringe feed her - the goal is that she keeps eating. If you make the slurry, just leave it in a bowl - warm it up a tiny bit in the microwave to make it smell a bit more appealing. You can also try making it with some apple juice or pumpkin to make it a bit more yummy, but if she is eating and pooping, then don't worry too mcuh - she will come around I think. You only need to syringe feed her if she was eating absolutely nothing at all.
