Trying to get food down her and keep her hydrated... vitamins in her water or dribbled down her beak..... Do you know how to tube feed? If you can find a good sized syringe and a soft rubber tube you can try. I use the parrot handfeeding formula. Mix it up to grit or oatmeal consistency. You want the tube a little longer than the length from mouth to croup, but if you have a shorter piece then just go slower. Taking the tube aim for the immediate left or right side of the throat, in kind of and up and back/side motion... AVOID THE HOLE RIGHT BEHIND THE TONGUE !!!! You want to go over that and into the throat. Sometimes I hold the bottom beak and tongue with my fingers of one hand while having someone shine a light down the throat. Slowly push the tube down the throat, it should slide easily, if not start again, you will see the tube move under the skin. When you get to or as close to the crop push in the syringe slowly and watch the croup fill. It is better to have too little then too much in the croup, as it can back up the throat and aspirate the bird. When you have given enough quickly pull out the tube in one motion. Sorry you have to go through this. I hope she does not have internal injuries and will perk up for you.
