Last night and this morning this little one was doing well. It was about half zipped when I went to bed at 8:30am. The kiddos told me that it was still moving around noon...but I didn't check it. When I did, at 2pm, it was too late. No movement so I took it out of the incubator and started to peel off the shell. It had made it about 3/4 of the way round. I thought maybe it had gotten its head stuck under the membrane and suffocated but after looking at its abdomen wasn't so sure. So.... do any experts out there want to enlighten this newbie?
