The Waiting is the Hardest Part...

You don't want the air cells to shrink at this point.
You want them to get larger.

So high humidity could shrink them right?

I always thought the opposite

Too high humidity won't allow the eggs to lose enough moisture which can lead to the chicks drowning in there but this usually happens if the humidity it too high throughout the whole process.
There is no need for higher humidity until you see an external pip.

I’m still trying to grasp this but this article that I found last night leads me to think that if humidity is too high, the air cell will be too small and if the air cell is too large, humidity is too low.

Always follow the manufacturer’s instructions for humidity and temperature; it can vary among different incubators.

I say throw the manufacturer's instructions in the trash.

This is correct but this is for the entire incubation time.
Come lockdown time you want those air cells getting bigger by the day.

that would be just way too simple

I meant to write, “Air cells” not actual chick - I think they get too big when humidity is too high but what the heck do I know!!!

if humidity is too high, the air cell will be too small.... and if the air cell is too large, humidity is too low.

Pretty much. Have you been tracing the air cells when you candled during incubation?
I do it on day 7-10-14-18. Sometimes adjusting humidity based on cell size.
I leave them alone after day 18.

It won't hurt a thing to candle them right now real quick.

Yah every hour on the hour, right?
