day 27 of guinea hen hatch under broody hen--please help

[corrae]

I'm hearing peeping from the guinea eggs I set under a couple hens. I live in NW Colorado--and it is HOT and DRY. Should I gently spray either the underside of the hen or the top of the eggs w/a little bit of water to help the keets hatch out? I understand the humidity should be relatively high. Please advise!

I am sure the hen will keep the humidity where it should be but then maybe some more knowledgeable people will chirp in here. Hens have been setting on and raising babies for eons so I tend to think to just let them handle it.
