Shell coming off the eggs!!!!

[denco5]

I have 7 eggs under a broody hen, they are set to hatch on Wednesday. Two of the eggs have had the shells start to release from the egg, only a thin membrane is left. The chick is moving, no chirping, in there but most of the shell is off.

What do I do? Do i help or let mother nature do its thing?

Thanks in advance
