Eggs not wiggling on day 17/18

[Lilaby Babys]

yesterday I was looking for any wiggling eggs but couldn't spot a single one and today is now lockdown and I only see one wiggling and the rest arent moving. Please tell me this is normal and they arent dead, My humidity and temp is perfect. Do some eggs just not wiggle before hatching please help me out.

They don't always move. I'd listen for peeping

Thankyou so much I was scared

Understandably! Even though I know that I'm probably imagining it, I still get worried about hatching eggs
