If it's cold where you are, then yes, I'd bring her into a warm place. You could crate her overnight so you can monitor her better, see how she's doing in the morning keep an eye on droppings, eating and drinking. Sometimes they can have a secondary bacterial infection if the worm load was heavy and damage was done to the intestinal tract. If she doesn't look any better in the morning, then I'd do a round of amoxicillin, 57 mg per pound of weight twice a day for 3 to 5 days. You can get that as fish mox without a prescription, some feed stores may carry it, or you can order it on line. I mix the dose in softened (not melted) coconut oil and freeze it til firm on parchement or waxed paper. Then give orally, the coconut usually goes down easy. Amoxicillin is usually well tolerated. Others may disagree, but I deal with roundworm all the time and this is what I do if a bird is not well after worming, and droppings look abnormal (which your birds do to me).
