One thing that needs to be stressed to those new to hatching, is that even under ideal incubator conditions 21 DAYS is just the most common baseline for hatching eggs. Many chicks can take 23 days. Some pip internally and fully hatch in hours while others will be 24 hours or more. Just because the chick started to external pip and has not fully hatched in 4-6 hours does not necessarily mean there is a problem. I have seen many chicks take over 48 hours from internal pip to full hatch.
Knowing when you "can" safely assist and when to walk away and let them do it on their own is something that only comes with hatching hundreds of chicks. For the most part I agree with the hands off approach, but there have been times when something wasn't quite right with the incubator and it was not a factor of less than thrifty chicks. At that point I will assist where I absolutely have to.
