When Should I Give Up on Incubation?

[astronomer]

Ok, not sure how good my humidity sensor is, but I'm getting about 80% RH at a temperature of 99F.
I gave up on the egg laid May 30th. Hoping for the other 3 to hatch.

80 seems VERY high

Ya, i'm really confused. I'm seeing anything from 40% to 90%. This can't be that complicated if ducks do it themselves...

Ok. I prefer a lower humidity! I aim for 35. You want to go lower at first higher for lockdown. If I were in your shoes, I would aim for 35-40 right now.

If the incubator doesn't have a fan, the temp of 99 is way too low... should be 102, I thiink.

It does have a fan. I think the humidity is too high. I'll decrease and see if the air sac gets bigger. My June 9th eggs are getting real close at 22 days.
