Well, the first sad note to this hatch. I am afraid we lost the wrong end pipped Rock egg.
I had checked it shortly after I noticed to make sure there was a hole in the membrane, but I don't know how long after it had pipped that was, and when I peeled back the membrane a little later on because it wasn't moving at all, I could barely see the tip of a beak deep in the crack, and it was not moving. I wondered if it might have pipped a vein too, because there was blood on the membrane when I first noticed the shell pipped off. SO frustrating that it got this far, only to fail because of a malpositioning problem!!
On a happier subject, the other Rock egg that had pipped in the right end is now properly zipping and should be breaking out soon!
There is also a large pip in one of the Delaware eggs finally, and there are two more EE eggs with pips.
I have to keep reminding myself that day 21 does not end until tonight and not to panic if all the eggs have not pipped by now!
Will keep you all updated.
