Well...at this point. I would start giving it vitamin drops every few hours. Best thing is nutri drench if you have it or polyvisol infant vitamin without iron. U can also put a bit of xxx antibiotic on the cord. Did it bleed a lot when u helped it hatch? It may have lost a lot of blood. Sometimes..the reason chicks don't hatch normally ..is cuz something wrong w them..even after they pip...
