Today is Day 19, right? They are in lockdown so don't open the incubator.
From what you said earlier, they should be hatching in two days. It's too hard to tell from pictures outside the incubator. What I do is candle on Day 17/18 before they go to lockdown.
Welcome to BYC!! :frow
Chicken eggs wouldn't normally be pipping yet, although it does happen. They usually won't until another day or two.
You won't usually see much movement at the end of their growing because there's not much room to move.
Relax! 😊
