Help- My eggs are 22 days, I heard chirping on day 20 but no chicks or even pipping yet.

Hi. The chicks are still under mum. It's been over 24 hrs and she hasn't moved from the nest. Is that ok or should I lift her to check the chick ( I haven't heard it chip since yesterday.

I've just been out again. The chick was dead. I am gutted. The broody are still sitting 5 eggs, I'm considering moving the chicks once they hatch
