It has been 12 hours since the inital pip, so we have decided to help. We pulled off part of the shell and it's a wonder how any chick that fills up the entire shell ever gets out. It's head had definitely no room to zip. I had this same problem with my last bantam eggs. The chicks were so large that their legs were wrapped around it's head. Does anyone else have this problem with bantam eggs? I have never hatched standard eggs, so I don't know if it's just bantam eggs or any egg that has so much trouble.
