HELP day 18 and air cell too small

[1 Critter Camp]

I have had a very successful 18 days of development. I have opened the incubator only two times and have added water via the holes on top. ALL eggs that were fertile have developed and moving wonderfully.

According to the diagram I found on line, the air cell for most of the eggs are about like they should be on day 14...

What can I do to increase their odds of hatching?

Thank you for your help!

In this case, I would consider removing the water you have in there, not upping the humidity when you lock down, but just stop turning them. Keep a really close eye on them and don't up the humidity until they start pipping, with any luck they will lose enough water to make up for a few days. Does your incubator have humidity control?
