Should I assist emergency

[Bigandlittles]

An egg pipped yesterday around 1pm. It pipped on the underside of shell. I have seen no progress since then. Should I be doing something to help this chick or should I let him be?

I also have one that has pipped at around 5 this morning but it looks unlike the other pips I have seen.

I don’t do chicks but I do ducklings and if no progress after 24 hours I do start to help
Take a little in the area they pip to see What’s going on
Check for veins abc chewing motion
If no veins and bird isn’t chewing I finish the zip and let them try to push out
