Well I've always read/heard don't help, that they get out on their own or they won't make it.
My personal feeling is if its going to die in the shell, am i really hurting it if I help? I mean it wouldn't be underdeveloped, so why not help?
Someone clarify the "why" for me please
I've read the same on just about every site I've been on On my last hatch I had one pip about 1/4 inch and then nothing. I watched for about 8 hours and could see his beak moving in the hole but no more shell removed. I lifted the lid part way and my wife reached in quickly and got the egg. A closer look revealed he didn't have an egg tooth. I took an ice pick and went around the shell careful not to puncture the membrane and connected his hole. I use a warm paper towel, wet the membrane and the next morning he was running with the rest of them. I think you just have to use a little common sense and it's all not chiseled in stone.
As far as the baby's knocking the eggs around, when the 24 of 25 hatched they were rolling them around like marbles but didn't seem to bother them at all. This is just the experience of two hatches so just take it with a grain of salt. Good luck on your next one! I have 60 eggs in the incubator now!
Edit: I forgot to mention I have a broody BO hen that can't be broken unless you put her in the stew pot so I gave her 8 eggs yesterday and she looks like a statue sitting in the nest box.
