Around 3 o'clock an egg began to pip. By 4 it was furiously zipping around the shell. It seemed very strong and was chirping the whole time. All of a sudden it stopped about 2.5 hours later. It made it half way around already. No movement, no chirping. What should I do? The membrane seems opaque where the shell has come off. Humidity was about 65, but is now up to 70. One spot of the membrane seems red inside. I know it can take a while and maybe it is tired, but with no movement or sound I am worried.
