I had a clutch of 5 eggs, 4 of which hatched successfully without incident yesterday.   Am using the Nurture Right 360 incubator.  The last egg was heard chirping yesterday, but today has gone quiet.  I was concerned that something had gone wrong, so tried to candle the egg quickly (I know the worries about shrink wrapping -- good news is that the room the incubator is in is relatively high humidity, and the incubator recovers humidity within a matter of seconds once closed), but can't see anything, not even the air cell that was there before.  Is it too late for that one? Worth trying to help?
Thanks y'all

  When the others were playing soccer with him/her and chirping around the incubator, s/he was chirping, but never pipped.  I'll sit with the current safety hole for maybe 12 hours before going further, or if there's no response you think it's worth expanding the hole a bit (staying within the air cell area, which I've marked from earlier days)?
