Day 17 air cells

[KellyMP]

I am on day 17 with my eggs, tomorrow evening will be technically when I put them in the incubator 18 days ago. Some of the eggs seem like their air cells are in a good place, but some seem too small. Is there anything I should do over the course of today and tomorrow to remedy the eggs that have the smaller air cells?

For reference, in the first picture, the two blue with the brown in between all seem to have rather small cells compared to some of the eggs to their left
