Good night Cynthia12
If someone else is still up with experience, 2 of my eggs that had pipped about 10 hrs ago, started zipping about 1.5 hrs ago. They zipped for about 1 cm and then stopped & haven't done anything since then. How long shall I leave them alone before intervening. The little bit of membrane I see is white, there is not much else I can see so far. I guess I am pulling an all nighter today (again)
