First time hatching with an incubator... about half survived to lock down (shipped eggs - about 1/4 didn't look fertile/didn't develop at all and 1/4 died during development?) I was having trouble getting the humidity right - and I was worried about getting it high enough for the 3ish day lock down. It is 70 % on day one. I know it should be 60-65%. Is that high enough to kill? Should I open and take some water out? Is it too late?
