I have a concern. I have a muscovy duck that just hatched 11 babies fine over the course of the last 2 days. The last one hatched over 24 hrs ago. She still had 2 eggs and I figured they were bad but when I checked last night one had a crack in the shell so I put it back. I just went and checked and there was no progress so I took it out and listened and heard nothing so I pulled off part of the shell and all of a sudden it started chirping and pecking inside but not where I had pulled off the shell. I tried to put it back under her just how I found it but I'm not sure if he is stuck or not. There is no hole through the membrane. Any advice?
