You did what I would . I really never look much at air cell on shipped eggs . Everything I've read and been told is if you get 50 % with shipped eggs you've done good .
The things that concern me most are if their cracked and are they scrambled but you can't really tell without cracking them open. Depending on what and how the hen eats yokes can be lighter and are hard to see sometimes .
The cell should be the proper size for the age of the egg.
Do what you did with the second hatch Banty and maybe have a good hatch

other thing keep the
We're already hitting close to the 90s here. The school hatch went well for them they hatched 26 out of 41 . and the students loved it . they want to do it again next year
. I'm thinking about building a full view Incubator. both wild turkey eggs are growing right along.

good luck
