So sorry you are having to go through this with Ruby! It is so heartbreaking!! I would say just keep her warm inside and let her rest tonight. She can build up some energy and maybe you can get something down her tomorrow. If you have a syringe without a needle that would really help you. Just drip water on the top of her beak and she will naturally drink it. See if she would take a small piece of bread because you could then soak it in some yogurt. Do you have any vitamin/electrolyte drops. I get mine at TSC. Please let us know how she is doing!! Saying prayers for you and Ruby.
