chick hatched too early and isnt walking, drinking or eating

My mom decided that the egg was ready to hatch and broke it open. The chick was covered in blood and so far has survived 2 days. She is very talkative but refuses to drink on her own and eat on her own. She isn't walking either. She tries to walk but I think she has splayed legs. I put a little vetwrap cast on her legs and gave her a nice surface to walk on but she won't even stand. She leans to one side when she lays down and keeps one wing up. WHAT DO I DO????
