As a newbie to incubating l have learned the following. What I'm going to say is my personal opinion and only my personal opinion based on my results and experince. DO NOT, EVER NEVER, UNDER ANY CIRCUMSTANCE REGARDLESS OF YOUR MATERNAL INSTICNT HELP A CHICK OUT OF THE SHELL. There is no good result from it. It's already unnatural to incubate eggs. Imagine taking that further. It's bad news. Some chicks survive the help but most die anyway. The ones that do survive face a life of issues inflicted by you which include stunted growth, leg issues and many other unnatural problems. Let nature take it course as nature knows best. I know it's tuff seeing that cute little beak peeping out a hole and your totally convinced he/she can't get out without your help but I assure if it is meant to be it is. More importantly, if it's not, it's not.
