We got 14 out 18 out of the incubator last night, the rest were showing no signs of progress. Right after that, two more pipped. This one started to zip last night and has been like this since maybe 9pm. The other unzipped and was out in minutes this morning. It's breathing and chirping but not making any progress. They're not even due until today but I figured 12 hours can't be good so I tried to help just now to see if I could chip a little more away from the zip and I don't think I can. The one piece of shell is stuck to him. I don't know what is normal but I'm afraid I'll hurt him. I put a drop of water on him earlier and again now. Can I do anything else? Can I help the zip at all without hurting him? It can't be good at this point right?
