Two days ago one of the eggs in my incubator pipped - then zipped about an inch. Then it stopped. Over 36 hours passed and nothing else happened. I didn't hear any chirping and I couldn't detect any movement. I would even look through the glass top of the bator and shine a flashlight along the zip to see if I could see any movement inside. Nothing. Meanwhile the three other chicks hatched. I waited another 12 hours and finally decided the hatch was over and that the un-zipped chick had died in the shell since 2 days had gone by since he'd started zipping. I put on rubber gloves to finish breaking open the shell to see if I could figure out what happened to it. As soon as I peeled back the top half of the shell, the chick started moving and then started chirping. I was in shock because I had thought for sure it was dead. I quickly put it back into the incubator where it promptly - within a couple minutes - finished hatching and is now running all over the bator and chirping madly. I'm still shaking my head in amazement. Has anything like that happened to anyone else?
