how does a broody take care of the humidity?

[missychicky]

I have a broody on eggs just about ready to hatch. What does a broody hen do to get the humidity up? Do I need to do anything to help her with it?

She plucks her breast feathers so the eggs are against her moist skin. If they needed human intervention, they'd never hatch babies in the wild, so nope, you don't do anything.
