Sigh... Can you bring her inside where it's warm? Sick birds need to be kept warm, 80° to 85° is ideal. She's probably also dehydrated and will need fluids and I'd start with 60ml every 4-6 hours.
DylansMom is correct, it's not usually the disease that kills them, it's dehydration and starvation. Bad news is once they lose too much weight they don't usually recover. @Birdrain92 , this is an emergency, if you can find a vet to see her today that would be your best option. Do you have fish-zole, Baytril or Safeguard? Can you go to
Tractor Supply and get a large syringe and to a
Petsmart to get a tube, babybird food and metronidazole?

Supportive Care
SICK-BIRD ENCLOSURES
Sick birds are often hypothermic and should be placed in heated (brooder-type) enclosures b (Fig 7.7) in a quiet environment (see Chapter 1, Clinical Practice). A temperature of 85° F (29° C) with 70% humidity is desirable for most sick birds. If brooders are not equipped with a humidity source, placing a small dish of water in the enclosure will often supply adequate humidity. A moist towel that is heated and placed on the bottom of a cage or incubator rapidly humidifies the environment, as indicated by the fogging of the acrylic cage front.
FLUID THERAPY
Oral Administration
Oral administration is the ideal method of giving fluids. This method is more commonly used in mildly dehydrated birds or in conjunction with subcutaneous (SC) or intravenous (IV) therapy. Oral rehydration (30 ml/kg PO q 6-8 h) also may be used in larger birds (eg, waterfowl) that are difficult to restrain for parenteral fluid therapy.
ORAL NUTRITIONAL SUPPLEMENTS
Below are listed some of the oral nutritional supplements that can be gavage-fed to debilitated birds. Various hand-feeding formulas are on the market and, as a whole, are far superior to the homemade formulas used decades ago that contained monkey biscuits, peanut butter and ground seeds. Commercially available hand-feeding formulas for baby birds are often utilized in the treatment of sick and debilitated adult birds. The quantity that can be fed at one time to a sick bird is greatly reduced from that of baby birds. On the average, a baby parrot can accommodate 10% of its body weight per feeding due to the elasticity of the crop and its rapid emptying. Adult birds have a greatly decreased crop capacity, averaging 3% of their body weight. Additionally, sick birds are less tolerant of food in the crop and care must be taken to avoid regurgitation and/or aspiration. A sick or debilitated bird should always have its hydration corrected prior to attempting to initiate oral gavage-feeding.
