Hello,
I'm so sorry to hear if all of this happening to your African grey! I'm so glad you git her back.
Can you describe what attacked her? Because to me what you describes is neurological damage and nerve damage from crushing injuries. Is she on antibiotics if this was an animal attack she needs antibiotics right away. As animals carry bacteria that causes life threatening illness in parrots.
Some of this can improve as swelling goes down. You need to keep the bird calm abd quiet in a small cafe so nit moving around to much. With easy access to good and water. Be careful with ways as she can drown in it. Offer high calories foods, it takes twice rge normal calories to heal. You may need to get baby bird formula and feed, very carefully so she doesn’t the aspirate. Adult's can not take very much at a time, not like babies at all. You just want to use a spoon or drip a little in the front of the beak at a time. Do not tube, or try and put in crop, as crop will rip or aspiration. Adult's aren't like babies. I hope she can snd will eat enough on her own, that she doesn’t need support feeding. But with 2 of my sick birds I've had to do this. It takes a lot if calories more than double what tgey normally eat to heal. First feeding a little running ( careful about choking), because they often aren't drinking enough, then by 3rd you thinking up to yogurt like thickness.
Support by warmth us also very important. Keeping their environment 80-85 f helps thrm burn less calories. And promotes healing.
How long ago fid this happen? I've seen creatures that have recovered a lot with time and support.
Special nutritional requirements for debilitated birds
Extra nutritional support for debilitated and diseased birds is vital and plays an essential role in ensuring recovery of the avian patient after disease or debility. Enteral nutrition is currently the most usual method of supporting the debilitated patient, with parenteral (intravenous) nutrition still being in its infancy in avian therapeutics.
First, fluid requirements should be assessed, as any animal will succumb to dehydration long before starvation. The reader is referred to chapter 14 for a more detailed discussion of this topic.
Second, energy requirements should be estimated. These can be calculated roughly from the MER by multiplication as follows:
Starvation = 0.5 × MER
Trauma = 1.5 × MER
Sepsis = 2.5 × MER
Burns = 3–4 × MER
From these crude estimations, a rough idea of the levels of nutrition demanded and the energy concentration of the diet can be derived.
Third, protein requirements should be evaluated, as debilitation will increase amino acid and protein turnover. This may be through the increased use of proteins in the immune system response, or for repair of damaged tissue or simply after using tissue proteins as an energy source."
