hmm ok so 80-100 grams is substantial is there a possibility of parasites? also can you provide pictures of the stool? and if it is diarrhea that would explain the dehydration, I would recommend monitoring her closely and maybe giving some more horn worms but not too many as she can get stuck in a vicious cycle of having that water having diarrhea and then needing more water. I would also recommend trying to lower stress as much as possible which I know seems pointless but honestly not much else I can say, oh also remember I AM NOT A VET THIS IS SIMPLY ADVICE TAKE EVERYTHING I JUST SAID WITH A GRAIN OF SALT.
