Great postYes, Gatorade has electrolytes designed to help keep human athletes hydrated. Tractor supply sells a product designed for livestock that might be cheaper on the long run. With this kind of head trauma you may start to see neurological signs: head tilt, staggering, blindness and so forth. While there are drugs to help this, most folks don't want to spend that kind of money on a chicken. However, in these cases superb nursing can also do wonders. The best thing to do is keep her warm-the fact she is sitting in her water dish might be an indicator of fever or an attempt to relieve pain: similar to humans applying a cold cloth or ice to reduce body temperature. If you note open mouth breathing make sure she is not too hot.
Remember to keep her as stress free as possible-keep nosy people and animals away from her. In a few days if you feel it is necessary to apply ointment to her scalped area-use something simple-neosporin. I like to use a mixture of _half/half betadine/mineral oil applied with a q-tip to the area-don't have to use much as it will spread on its own. Chickens don't seem to mind this mixture as much as ointment which has a tendency to make them shake their head in an attempt remove the goo.
If at any time she becomes stressed from handling stop everything. Let her be and allow her to recover. Reevaluate the situation and gauge what you think you should do.
Good luck with her! Sometimes these chickens surprise us!
