How to let broody hen hatch eggs?

[Peony7]

*** update. Never mind, I looked again. Found it!

I looked quickly but didn't see a reference about the process of letting a broody hatch eggs. I'm sure there are things I should do. Can someone send me the info I'm sure is already posted here somewhere?
Thanks!

Really they do all the work and just leave them alone but make sure they are safe ....
