Chicken egg air cell day 14

[Boobumpbeanbear]

Hello. I have been trying to hatch chickens for the first time, but out of 4 eggs in the incubator, 2 were infertile so only 2 left. i have 1 egg i am unsure if the air cell is the correct size.I have dry incubated as the humidity here is quite high and it has stayed between 30-40%. They were put in the incubator at 8am 9th june so does that make today the 15th or the 14th? Also when is best to lockdown and how high should i put the humidity?
Thank you very much for any help. I really would like to get these little chickens to hatch. This picture is the air cell on day 6/7 and then last night.

Those look like fine air cells to me. Some eggs get lopsided right away, some stay pretty even until they're almost ready to hatch- I was worried about mine my first hatch, but I was weighing them so I knew I was getting the right amount of weightloss. 70% is a good humidity to aim for. Most people lockdown the 18th, but you can do it a bit earlier if you like, I've even see people say they don't do it until they see an internal pip. There's actually a fair bit of wiggle room.
Days counts completed days, so it's the 14th.

Thank you so much for replying, I feel much happier now. I have no idea what I'm doing and i compare to all the charts but then I get more unsure.Ok so I will aim for 70% humidity (should be easy here) from the 27th(18th day). Thank you very much.
