Your thermometer and bator temp is way off. Take the time to calibrate against a known to be accurate medical quality thermometer before incubating again. (bulb type or digital. Medical grade are almost always guaranteed to be accurate to +/- .2*F. While doing the ice water calibration is recommended, I do not use this method, b/c a thermometer that is accurate at 32* MAY NOT be accurate at 100*) I calibrate by placing thermometers in a bowl or cup of water at approximately 100*, wait for them to equalize, and then compare the temp readings. Be sure you do not let them touch sides or bottom of the bowl.
If this weak chick is the first one to hatch, I don't hold out much hope for her survival or long term viability. Incubation temp too low can cause all sorts of developmental abnormalities. You can wait on the rest of the eggs, but most likely will have to call this incubation a learning experience and move on. Please read ALL of "Hatching Eggs 101" in the learning center before incubating again.
