The other day I was putting eggs into lockdown I dropped some eggs. Several broke and that was the end for them. several chipped or dented, and a couple the shell peeled back in a couple spots leaving the membrane over the duckling.. I felt terrible, but decided the ones with intact membrane were going in with the rest. One actually tried to hatch several days later, and was partly out, but the membrane got too dry and 'shrunk wrapped" him during the night. He seemed fine, but I guess he got tired and gave up and passed away--If it would have been during the daytime and I had seen it, I totally believe he could have been saved by dampening the membrane so he could get all the way out..The other 2 got too dry and shrunk wrapped.. If this happens to you and the chick is still alive, At hatch time I would make sure the little fella is kept damp so he can have a chance to get totally free..
