How much longer...

[akpeeps]

should I give an egg in the incubator before I call it done? I have one left that I put in on 10/3. The one other two from 9/29 and 10/2 hatched right one day 21.
I candled tonight and there is a large air cell but you can still see some veining at the lower edge of it and where the chick is. While I didn't see much movement, at the top of the air cell I could see some pulsing. The other two were all chick and air cell at day 18. Should I leave it alone for another day or two?

I guess I should add that I have a LG with a fan. The temp has been consistant at 100 degrees, only falling to 99 a few times. The humidity has been a pain in the butt to keep consistant but had varied from 65-71 during lock down and was 50-60 before that.

many wait till 25th days, and there's no harm keeping the egg inside bator as long as it don't spread any bad odor, since bad odor is a sign of nearly explode egg.
