X2Sorry that she is still doing poorly, but this can happen when you have a problem hatch. Do you have a syringe and needle to withdraw it from the vial? I would give 0.2 ml orally into the beak a drop at a time, 3-4 times a day for 3-5 days. The B Complex, can be cut into 4 pieces and crush a 1/4 tablet onto some small amount of her chick crumbles. A drop or two of water can get the vitamin to cling to feed.
You need to get it in her ASAP or you might lose her. Good luck and I hope she makes it!
