I have one chick that had started pipping 12 hours ago. I woke up this morning to check on the chicks and this one partially unzipped and has a pool of blood under it in the bator. When should I help? It is moving in the shell but a little disoriented. I do see its beak and it looks like its grasping for air. I have read all the dangers of helping too soon. What should I do?
