First of all keep her warm if she is dehydrated her body temperature is dropping. I would put a heating pad under her but not touching her at anytime. Just under everything. It sure sounds like she is dehydrated and may not be able to overcome without moving right away. I've had a bit of luck putting something sweet like syrup into water then with a spoon full of this sweet liquid hope she will accept it. Hold her close to you with her wings down so she cant resist or flap her wings causing an accident. Try then holding a spoonful (preferably a small plastic throw away spoon) of the sweet water to her beak. See if she will accept it if you point her beak into it. If so, offer her more by doing this as many times as she will take some. If she wont, gently force open her beak hoping she will accept it when the spoon is partially put into her beak with you holding her and forcing it there. But dont force the liquid down her, just the spoon of sweet water held between her beaks. Now see if she will want to accept a bit if you give her a bit of slack. Be cause it could go into her lungs and cause further serious problems if you force it. You can try an eye dropper and put just a tiny drop into her lower beak and she may raise her head up and take it. If no dropper just use the spoon pouring a very small stressing small amount into the lower beak with her head straight ahead and not raised back. We are hoping she will voluntarily raise her head back and accept it. If that doesn't work, put a very small amount of the thick syrup with your finger into her lower beak. I'm aiming at hoping she is now going to want to take some water from the spoon from you on her own or the dropper if you are lucky enough to have one. Anyway, if she starts to take the sweet water after applying the syrup, then give her all she will take. If she does you can also wet your fingers into some of her laying mash or what ever food she eats and try to Simi wet it to kind of stick a small amount of it together and put some into her lower beak. This is only after she has accepted water. Hopefully she will take it. Or if she has pellets put one briefly into the water to soak it, then place into her lower beak.
I believe if she voluntarily accepts it enough times when you work with her, she will start eating again.
But if I had her, I have the supplies around and I would give her a tube feeding of gravy like consistancy of substance directly into her crop. Doing this maybe once or twice would probably put her in order. You would need a medicine syringe with a rubber hose like aquarium hose about 3 inches long. Only if you want to do that, I'll go into the details of how that can be done. I'll come back to the thread in my spare time for a few hours to see. Or maybe another member here will guide you. I hope your chicken pulls thorough.
I am sorry.
but it's hard
Reading the whole thread would be a good idea.
