desert humidity 25% sufficient?

[abqferreira]

Today is day 18 for my broody hen and her eggs here in New Mexico, but the humidity is about 25-35% over the next 24 hrs according to weather.com. Do I need to do anything to raise the humidity in the coop for the eggs or will they do ok? I'm seeing a lot of posts about how nature knows how to do this and not to worry, but I also see posts from people obsessing about the humidity in their incubators when it's 60%.

Thanks in advance for any suggestions!

Hey I live in Southern Utah. We have very dry air, and I haven't supplemented my broody hens at all. My broody hens like to pluck their belly feathers. I am thinking the skin to egg contact may provide humidity via the hen.

It seems like there's a different need for humidity in incubators eggs, is this true? I'm hearing that broody hen raised eggs just don't need the same humidity levels. I'm curious if anyone knows the science behind this reasoning. Has anyone with broody hens had problems typical of low humidity?
