So I had this chick that was one of the last ones to hatch and it had zipped about an inch so far but to me it looked like it was kind of stuck where it was because no matter how much it moved it's head, it never came into contact with the shell. I decided to wait until morning to help it but when I checked the next morning, it was dead, but with a twist. It was covered in yolk, like it looked like the yolk had burst and it died right there. It hadn't made any progress, it was just still there, covered in the yolk, and dead. Anyone know what happened? Could it have pushed so hard it burst the yolk that hadn't been absorbed?
