My quote was to the last poster. Not sure what kind of eggs they are.AmyLynn2374- the OP is hatching quail, not chicken eggs. They typically take around 17 days to hatch, so they are quite late.
I agree your temperature must've been pretty low. You'll probably want to calibrate your thermometer before you incubate again, or get a new, more reliable one. I just got myself a Brinsea spot check, its pretty awesome, super accurate.
Good luck.
