My first hatch I had to help, the next I didn't and this 3rd one I do again. I play over and over in my head the scenario's. This hatch? Some are zipping and getting out, they seem to know what to do? Others will pip and stop....period. next day same hole no progress. I help them out (which I hate doing) and they do fine. It seems they pip and no zip and are in a position where they can't move around? Has anyone else dealt with the pip no zip? Pip not progress after 24 hours? My second hatch, nearly half hatched and the other half was all full or super close to full development but are dead in shell. Any ideas?
