Since she's weakening, I suggest giving her sugar water to drink. You can give her tepid Gatoraid if you have it, or mix a teaspoon of sugar into a cup of tepid water. If you have Poultry Nutri-drench, add a squirt into the sugar water. Let her drink it freely. If she's too weak to drink, you can syringe or tube feed it to her. Do you know how to tube feed? It would be the fastest way to revive her.
