Its day 21 and 1 of my 8 eggs have pipped the shell over 6 hours ago, since then nothing. I cant hear it cheeping. The other 7 eggs are still and these eggs were from my rooster that has gone to a better place. I would like to get at least 1 chickadee. Should I help,wait,what? I did have a humidity drop to 52% but it regained after anhour. Is it a gonner?
