Can lockdown be on day 16 or 19?

[Grade1Chicks]

I have my incubator in the classroom and day 18 for me falls on a Sunday. What do you recommend I do about lockdown? Is it ok to raise the humidity on day 16 or wait until day 19? I want to make sure there are no problems for the chicks to hatch. Any suggestions are appreciated!

I have lots of schools do hatches for me
Often they go in daily and I meet them on Sunday’s to do lockdown
That being said a few times we have already had internal pips on day 25 ( duck eggs )
So you can start lockdown a little early

So day 16 is better than 19?
