Dehydrated Chicken- PLEASE HELP

[HorseMadWhovian]

I've been away for a few days and I've come back most of my chickens are fine except one silkie, she can't hold her head up, shivers and is incredibly listless. I think she's dehydrated, what can I do to help, she is in the bathroom with a heater on low wrapped in towels, I gave her a drink and now she's kinda sleeping and convulsing occasionally please help I'm and desperate to save her.

Did they run out of water, or is the temperature very hot there? Is she showing any signs of wry neck that can be common in silkies, and may be a symptom of vitamin deficiency, head injury, or certain diseases? If it is dehydration, I would offer her electrolytes solution (SaveAChick, Pedialyte, or homemade) and give it with a syringe or dropper very carefully not to choke her. If she starts drinking on her own be careful that she doesn't overdo the fluids too fast or that could be harmful, too. Vitamins (which are in the SaveAChick electrolytes) may help if it is wry neck. or PolyVisol 2-3 drops by mouth daily. You sound like you are giving her what she needs. I hope she responds. Here are some links about wry neck:
