New to hatching

[Chickie Momma]

What is the optimal temp for hatching fertile eggs?

 

[Chickie Momma]

And what humidity % until the last week? I know for the last week the humidity increases, but don't remember the % for that either. Just got my hatching eggs

Temperature depends on your incubator and humidity depends on your location. Temperature should be 99.5 F in a forced air incubator, or 101.5 F measured at the top of the eggs in a still air.

Humidity will depend on your climate, location, and elevation. For me, I need to keep it at about 30% for the first 18 days, and then 65% for lockdown.

Thank you! The numbers sound like the ones someone told me a while back. I'm in north west Georgia not in the mountains.

Those are the exact temps and humidity I use too.
99.5 forced air and 30% humidity, 65%-70% at lockdown.
I don't use one of those fancy incubators either, mines an ugly box made of pink foam insulation, held together with red tuck tape ha.

That seems to work great for me. Last batch, 16 out of 17 hatched. 14 out of 16 the time before.
