I opened a hole- they're fine so far, yawning and fidgeting inside the egg. I also put plent of humidity to help. Seems like the membrane was dry...but I'm letting nature take its course from now
To add it was weird how it died though. It was a healthy moving chick inside the egg, breathing properly. Then it moved it's head up as if to pip then died right there. Any idea of the causes?
If you have any weak hicks try feeding them boiled egg yolk this will boost up there vitamin and energy levels, The rest can just be fed on chick crumb.
