Last night was day 21. At 10:30 PM I heard chirping for the very first time ever!!!! This morning I see a pip or a crack in the top of the shell. But, I don't hear chirping anymore and I don't see rocking. Last night my humidity was 81%. When I woke up this morning it was 63%. I added more water to the paper towels, so the humidity is now back up to 81%. Questions: Does chirping stop when pipping begins? Once a crack is formed, how long should it take it to get out of the shell? When should I help, or did it already die?
