They are very good at hatching quickly while we are at work.
If I am at home, the hatch takes DAYS from first pip to last out.
If I am at work and I get the call that I have a pip after lunch, I rarely make it home to see the last chick out of the shell.

Enjoy your new Fuzz-butts! They'll all be waiting for you by the time you make it through traffic!
