Did she have labored breathing before you gave electrolytes? How did you administer them?
I would try holding a cup up to her beak and see if she will drink on her own. If you do have to syringe fluids into her, then read the article below and study the photos.
She may have aspirated fluids?
She has bruising near her abdomen - you see green or bluish colored skin or she's bloated? How do you know she has bruising? IF she's bloated, what does it feel like...air under the skin or fluid??
