broody Hens And Humidity

hi all its been playing on my mind that all the brooder chickens and quail hens that hatch eggs how do they make the humidity rise with their bodies or do they just leave it natural thanks alot.

On the last few days when you would raise the humidity in a incubator, you spray the eggs or drip a bit of warmish water on them when the broody is off the nest having her daily feed,water..etc..

o right i was just wondering if the hen does something like sprinkles water on them herself of something like that but thanks for asnwer the questoin sam cheers.

what i dont get is.. if your incubating eggs naturally why the need to still spray/drip water on eggs? :S

lol i just wonder if the hen naturally turns the eggs does she still turn them during hatch date as they dont know when they are going to hatch unless some1 told them lol.

could be a good science experiment for you guys Why not put a thermostat/hygrometer under a broody hen and take regular readings of temperature and humidity

sam thats your job i will just write it down lol ive not got no hens but i can rwite alll the readings down lol.

Yeah....May do that next year

ive put eggs under my broody hens, i was just going to let them do it all themselves. my quails in the past have hatched their own and been ok.
