Small air cell day 17

[madjen17]

I am hatching for the 3rd time. I have 2 eggs at day 18-growing a big air cell and 2 other cross breed eggs from my own chickens on day 17 and their air cells are tiny! HELP!!

There's really not a lot you can do in a small single incubator. The reality is that different eggs lose moisture at different rates. That happens when incubating different types of eggs.
I've even had it happen when all eggs were of the same breed and same line of birds.
You don't really want to dry it out or your other eggs could have a problem. Without seeing the air cells, all I can advise is to wait till day 19 or early 20 before kicking up the humidity.

This is day 18 now. Very small compared to 2nd one who just turned day 19

This is the day 19

That doesn't look like it is close to day 18. At that point, much more of the egg should be dark.
