Day 20 of lockdown with Bantams eggs no pips

[Gigachad poultry]

So on the first of march around 4: pm i put 18 bantam eggs of some different types, but all bantams. It's day 20 of incubation and although day 16 through 19 I've seen them moving. There is not a single pip. I put them into lockdown day 16, because i've been told and read that bantams go into lockdown day 16 of incubation. Also i started counting the incubation the day after i put them in i think that's okay, or is it not IDK. I've heared peeping once or twice also while it was making this thread i stopped to check on the incubator, because it was either the crickets for the chickens and my beaded dragon Rex or the chicks, but i can't tell . When should i start seeing pips? I'm not going to open the incubator, because i think that's bad. Like maybe it could shrink-wrap the eggs or something? I really want to candle a few though. Please help

Leave it.
Don't open the lid.
Patience.

Did your eggs hatch?

Yup they are all getting super big, but sadly only 7 out of the 18 some eggs hatched.
