Muscovy duck eggs on day 39 and still no pips

[BOchickmama4]

Hi everyone, it's my first time incubating muscovys and I know they take 33-37 days to hatch and I'm Incubating 6 at the moment (started with 12 but they didn't start developing) on day 39 right now and there is still no signs of external pipping, I don't know if I should candle them as that would mean opening the incubator while they are in lockdown. I could make a safety hole into the air cell?? What should I do??? Is this normal?!

I would definitely carefully check them out. Generally if egg don't hatch by day 36 or 37 I generally check them, and end up tossing them. Eggs can explode if rotten so handle with care.

Were these shipped or local eggs?

They are eggs from my own ducks (Coco, Poppy and Harold) and it's our first time incubating any from them. The first 6 that we Incubate in this hatch never started developing, these 6 looked ok on day 30 when we candled them

What should I be looking for?
If I don't see movement should I chuck them out? I've heard about making a little hole in the shell into the air cell so they can breathe, should I do that??

That won’t help them unless they have internal pip
Have you noticed any bruising on the egg outside of the air cell ?
What day did you set them ?
What temp and humidity did you keep them at ? Did you calibrate a hygrometer and thermometer separate from the bator and set inside ?

8th may I set them.
I'll check for bruising, I used the brinsea 24 egg incubator

I can hear cheeping from 1 of the eggs and if I tap the others I hear tapping back

Are they internally pipped?

Are they internally pipped?

Yes,
I found someone who had hatched muscovys a few times before, she made safety holes in them and we are hoping for the best, we didn't see any movement so we aren't that hopeful, but...
