how many days does it take to pip?

I was just wondering how many days it usually takes the chick to pip the shell? I have a bunch of showgirl eggs in the incubator now and thursday is day 18 for them this is my first time trying to incubate so I was just curious how long I can expect.

It takes 21 days for eggs to hatch. But they can hatch a day or 2 early or a day or 2 late. The variation in hatching can be from lower temperature and ? Again, it is varied when they start to pip. Some just seem to pip and then zip, much quicker than others.
