I just hatched a batch of Sebright eggs, and of the twelve that made it to lockdown, eight hatched on day 20-21, one on day 22, and one is still half-hatched on day 26. He's been zipped since day 21, and has been making noise off and on the whole time. His shell does appear to be cracked most of the way around. It looks like the slightest effort would break it, and I don't understand why he hasn't come out. I originally said I wasn't going to help any of the chicks, but at this point, I'm sorely tempted. Surely he must be developed by now. And hungry! But I don't want to help if it means potentially breeding weakness into them, either. Any thoughts on why this little guy still hasn't come out? He's still cheeping pretty strongly, and wiggling occasionally. Thanks!
