If the chick can't hatch itself it isn't strong enough to survive. I learned this lesson a long time ago when I was hatching chickens, ducks, quail, and geese using Rose Colored Glasses.

This isn't necessarily true. I had a chick that didn't pip itself by day 23 or 24. I had to do it. This same chick, I discovered, only took up about half his shell space. I hatched him, he just layed there and made just about no effort to get out of his shell. He didn't have a pecking instinct for three or four days. We had to dribble baby vitamins and liquified chick starter down his beak to get some nutrition into him. For WEEKS he was about a third the size of his two female hatchmates, see pictures....
After that, he went through a massive growth spurt, and now, at six months old, he weighs a whopping 13 pounds, and as an Orpington, he will continue to grow and fill out for the next two years.
Does he look too weak to survive to you?
Just do what you feel is best. If you help him, he will have a chance at life. If you leave him, and you know for sure that he is stuck, he will definately die. JMHO
