Day 23 huge air sack, Chirping stopped

[Tpatterso12]

So I’m on end of day 23. At day 18 I outlined the air sac. Day 21/22 I could hear one chirping and see it moving. Chick hasn’t chirped in over 24 hours and isn’t moving. I candled all Of my eggs again today, and the air sac is huge! I do see some veins. Does that mean the chicks are dead? And if so, any ideas how that would happen? Humidity and temp levels were fine and they were locked down day 18. Thanks in advance!

They can hatch up to 25 days. Assuming you don’t know the answer to my original question then?

i would say keep on incubating and see the outcome.... could you show some candling pics?

There's an old thread here which outlines how to perform a float test for signs of life:

Hopefully your outcome is number 4!
