If the baby is still alive, I wouldn't be concerned yet. What I would be concerned about is it getting dry or moldy. Make sure you have some water in the incubator so when it's warm (i.e. the same temp as in the incubator), you can refill the fluid in the egg. If there's mold or bacterial growth on the inside, you should be able to use a q-tip to remove it.
If you try and take the baby out, you'll end up doing more harm than good. I would suggest you look and see if there's a twisted cord...that could be a reason why it's not hatched yet.
