Day 20, no wiggling anymore - help!!

[Shrubbie]

Hi,
We’re on day 20, 4 eggs in incubator - my 10yo daughter’s passion project.
On eve of day 18 the eggs were all wiggling so exciting…but then nothing on day 19 (we assumed resting), but now also nothing today day 20.
I’m wracking my brains- what’s wrong! We tried one last year in a borrowed Chinese machine, and failed - so sad - prob humidity/opening so I’m really worried and definitely not keen to try candling.

I did notice a temp drop earlier today - to below 37.5 - so I adjusted a tiny bit to get it back to normal. Now I’m wondering/overthinking…was that the point they died?

Please- advice anyone?
Thanks so much…

How long was the temp down for? Short term (a few minutes to an hour) are more problematic in the first 2 weeks. What is your humidity at?

Welcome to Backyard Chickens!

What breed are you incubating?
The eggs could be a little behind if humidity/temp was off.
I would keep the lid on and check for pips in the morning.

Hi, thanks, the temp has never been down or up significantly during the 3 weeks. I’ve just been fussy to adjust it tiny amounts of needed (change in weather).
It’s a Brinsea Mini Eco, nothing to See but eggs at the moment. I’m not at all sure how to check humidity as it doesn’t include that in the instructions but I’ll research it now…I just assumed given the model (for beginners) that the humidity was accounted for with the increase in water in the pot in the middle, which I’ve done.

I recommend humidity readers for future hatches

The built in ones are never really accurate

Yes, a hygrometer
