I guess i'd help it too if it is that far along, stopped and I was leaving for awhile.Help it out. I had one who had zipped into a weird position and couldn't right itself, so I had to tear the top of the egg off. He was so tired that he just laid on the floor of the incubator for awhile. I turned off the light and let it rest and now he's good as new
A lot of times chicks with dried membranes need to be assisted, otherwise they exhaust themselves and die. They just can't move around very well.
