I have had to help a couple times. Not sure if I HAD to help but sure felt like I did and glad I did. but I just zip a bit for them and let them do the rest hopefully. if they don't then I do a bit more and give more time etc. I helped 2 my last hatch and they are doing great. Then 2 I got nervous with since it seemed a LONG time since internal pip so I just put a safety hole in the air cell for them, barely the size of a tip of a pencil and let them be. They hatched on their own after that, but think they would have been DIS if I didn't do the safety hole.So far I’ve never had to help, I try to be out of the house since it’s sooooo tempting lol
