Duckling hatching - in lockdown

[LucyDuck]

Hi
I'd really appreciate some advice - first time hatching ducklings and want to get it as right as I can!
Do you all lower temp by a degree at lockdown? Have been running at 38 and so wondering if should reduce to 37 now?
Also had humidity at 55 pre-lockdown but seems a lot of variation for during lockdown. Some sites say 65%, others up to 80%. What do you all use?
And finally one of our eggs looks like below. Is that a blood spot in the air sac? Thought that was probably a bad sign? Duckling fine on candling 2 days ago. Now on lockdown so can't check
Thank you so much!!

I do not lower my temperature.
I also don't follow the no candling during lockdown.
I would candle the one blood one asap just to get a better look at what's going on.
Also I think 85% is too high.

How do your air cells look now?
Can you get a few photos when it gets dark?

Have it set at 65% at moment.
Just candled and large air sack, could see odd movement but looked like quite a lot of diffuse redness too... Will post some pics

Is this the same egg or different ones?

All the same egg. Didn't candle any of the others (except from a distance outside incubator to check air sacs looked ok)
