What should I do now? Live or cull?

Ok so I have this white Wilkie that is going to be three months old on the 11th of august. Well she wasn't support to be hatched but the Other chicks were picking on her egg so she was going to bleed to death. Long story short she lived but hatched with spraddled leg. So I thought I fixed it but I didn't. Now she is living with a very serve sprAdlled leg. One of her legs are straight while the other is waaaaay out in front of her what should I do
