Well 6 of the 12 eggs that were shipped hatched a day early on Wendsday, day 21 was thursday. There are no visable pips on any of the remaining eggs. How long should you wait to either break the eggs open to see how far along they made it or just dispose of the eggs. I attempted to candle on day 17 and all eggs were uniformly dark and i was not really able to see anything but an air space. I would think that if they were alive there would be atleast be a pip on the egg. How late can eggs hatch. The last time i had about a 3 day variance on the hatch from start to finish But i did put a couple eggs in the bater on day 2 so i assumed it was those that were a day or to late. Thanks for any help.
