What am I supposed to be seeing on Day 15? - Other things to look out for in Lockdown.

Hey all, new hatcher here!
I've never made it to Lockdown stage, so I'm a nervous wreck.
The egg is a coturnix by the way.
Should my egg be externally pipping by Day 15? I haven't noticed ANY movement. I thought I would notice maybe a small jiggle? Maybe even some cheeping noises.

So far it's nothing.
The incubator had been on about 40%humidity while for Day 1-14 and I've bumped it up to 50-55% because I'm staggered hatching.

ALSO: I've candled the egg (While rotating), and there was a small dark patch of the egg slightly going into the air sac, looked like a waning crescent.

The dark patch you are seeing in the air cell is likely shadowing- I usually see this before the chick internally pips- you can stop rotating this egg and just leave it be.
Very often I don’t hear or see anything before chicks hatch

Thank you so much!
This made me feel more confident, thanks!

I believe coturnix take about 18 days to hatch, so you may not see anything until tomorrow or even the next day?
