Personally, I would peel of some pieces of shell near each end, mainly searching for the bill to make sure the duckling has air to breathe, and also the other end should have the yolk sac. See how much is left to absorb. Coat any membrane exposed and look for heavy veins. It looks almost ready to hatch to me.
If you use some type of homemade thing to try to wait it out, temp too low is better than temp too high at this point.
Congrats!
