Could she have been dropped? When did you tape her legs and why? What symptoms caused you to do that? It's okay if she needs it but generally, that is a treatment for splayed legs.
My thinking here is possibly a neurological condition called wry neck, It can be treated but treatment isn't always successful. I'm not saying that it is for sure wry neck but it sounds like it could be. Wry neck can be caused by a head injury, a vitamin deficiency, somehow ingesting some form of toxin, or sometimes it's genetic. The first thing that I would suggest is that you find a way to get some nutrition into her. For tonight, Since she seems to be able to swallow water, I would soak a tiny bit of her starter food in water, mostly just make the water brown, you don't want any pieces of food to remain solid or she could choke.
Oh, you said you were giving her electrolytes, what are you giving her? Something like Sav a chick? or something else made for chickens?
