New to incubating. Advice please :)

Bought my incubator 4 weeks ago. I got 10 eggs off a friend and put them in. Set the incubator up according to the instructions.
All looking well. Come to day 18 I removed them from the tray. Today (26th) is day 21. One egg had pipped lunch time yesterday. I left it be. And had made further progress in the afternoon. And had been chirping through a pinky finger sized hole. Late last night another had pipped and that chicken had hatched this morning. The first to pip had made no further progress. I assume it had difficulty and didn't make it.
Since 3 more have pipped.
My question is how long should I leave the hatched chicken in the incubator before putting it in the brooder?
In your experience does it really encourage the others to hatch??
How long do your eggs normally take to hatch after pipping.
Thanks

The recommendation is to not open the hatcher until there are no visible pips or zips. Opening the bator can cause a decrease in humidity and cause shrink wrapping or difficulty in hatching.

Considering the eggs were all laid on the same day I expect there won't be too much longer till some more action
