My humidity has been between 65% and 70% since the first egg pipped and I have not opened the lid at all, not even once, so please tell me that it is impossible for the little guys to get shrink wrapped
I am just being a nervous nelly as I have 4 pips and 2 zipped and to start with they were really active and now they have come to a screeching halt. I know they have to rest etc, but the 2 that have zipped - the membraine looks still very intact with only a few slits here and there and I'm stressing that it is too tough or dry for them to break through.
