Here's the dilemma. Some people dont want to help, and think if a chick can't get out on its own, its not worth helping.
If you want to help, I would grab that one out quickly, and moisten the membrane (warm water with a qtip or your finger) and see if you can see what the problem might be. Dont pull the chick all the way out, let it do that part. Maybe it just missed a section of membrane and can't find the places still holding it together and is now too weak to break all the way out. Separate the membrane for it if you have to. Then quickly put it back in.
Trust your gut...
