29 day duck eggs, live, no pips or signs of hatching.

Should I up the temp back up again?

My incubator thermometer

The incubator thermometer cannot be relied upon. They are notoriously inaccurate.
I can almost guarantee, if you use a guaranteed accurate or calibrated independent thermometer

The thermometer lets you adjust the temperature and shows what temperature it's set on.

If they are still alive at the temp you had running before after 29 days I would stick with that temp. It would be good to get a second thermometer. It's not impossible that the incubator heater could start acting weird halfway through but if they are still alive I would go with what has worked this far.

I understand that but unless you have a reliable base temperature, you don't know what you are adjusting to accomplish. Until verified, you are working with unknown nebulous values.

Yeah, every single incubator I have worked with has been off temp. I mean it's only been 3 but still. I have to set two of them between 103-104* to hit roughly where I need them to be. If I set to 99.5* they die (and yes, I did this too when my backup thermometer was wrong. Killed several expensive eggs :/)

Oh no what kind of eggs were they???

I upped the temp back up to 102 degrees, put the egg racks back in, and candled the eggs earlier. They are still alive. No blood ring, and blood vessels were still visible. The eggs weren't turned for about 2 days, but they are okay. But the embryos do not seem fully developed so maybe they are muscovy eggs and not pekin eggs, since these eggs looked significantly different from pekin eggs when I compared the two. At first I thought they were pekin eggs because they looked a lot like pekin eggs.

6 were breeder (rather than pet) quality silkies $150/dozen, and then there were another two (I think that was around the same time) that were Indio Gigante eggs ($15 each.) however, I think there was possibly a different issue with the 2 Indio eggs that were fertile but didn't hatch. I'd have to check my notes.

If they've made it 29 days, it's probably not 102*+

And not turning it shouldn't be too bad. Though I will say you want to look at the Muscovy incubation thread on this forum. Make sure the vents are completely open for oxygen. Consider misting and resting the eggs each day. And pay special attention to the air sacs. You want to do everything (evaporation via misting, turning often enough-- not turning for 2 days is probably fine) to get those air sacs large enough because the goo will drown the ducks. And expect the hatching process to be long. If I recall it can be 3-5 days versus 1-3 for chickens.
