Did I kill my chicks?

Are you sure about this? I though high humidity keeps the evaporation rate low and prevents formation of a good air cell and so increases the risk of drowning upon pipping because they miss the air cell. While low humidity causes a larger air cell which is much less troublesome than small air cells. Could you please explain this more, 'cause it sure does make a difference when tweeking incubation.

Yeah, that explanation wasn't correct. If there is a very small air sac, that means that not enough moisture has evaporated through the shell, and it is because humidity was too high. In this case, you will probably have soggy chicks. If there is a very big air sac, it means that too much moisture has evaporated, because humidity was too low. If humidity was too low, you definitely won't get soggy chicks.

Gypsy07 and Suechick are correct. Sometimes no facts are better than wrong facts.
