    Some of my chicks seem too small in the egg but still moving and others are full but can't see movement also the air sacs seem to be a bit too small humidity was a bit high the first 11 days. Still air little giant with no auto turner and manually turned 3 times a day

    Are your eggs different breeds? All chicks are individuals and may just have developed smaller.
    At this late stage in incubation there is not too much you can do about the size of the air sac.

    For me I would just lock them down and see what happens. I see you posted over a day ago, have you got any action yet?
    Good luck :fl

    It's day 20 still nothing I lowered humidity in hopes to get air cell bigger but not feeling comfortable with that choice now guess we'll see what happens

    There is still time, your only on day 20 so still plenty of time for them to hatch. I would put your humidity up, they need high for when they hatch. At least 65% for lockdown.

    Did you count day 1 as the day you set or after a full 24 hours of incubation?

    Yes I did count the day they went in the Bator as day 1 and it did look like temps and humidity were good but I added thermometers and more hygrometers after that which read low so I don't know I've had some fluctuations I guess I'll shoot for the weekend

    If you counted the day you set as day 1 you are only on day 19 now.

    Day 1 should be counted after a full 24 hours of incubation. Say you set on a Friday morning day 1 would be Saturday morning, day 2 would be Sunday morning, day 3 would be Monday morning and so forth.

    Still plenty of time for your eggs to hatch yet.

    To simplify, if they were set on a Saturday, they should hatch on a Saturday - if temps were correct.
