humidity

just wanted to ask the first 18 days what should the humidity be around, have heard during this time between 50 and 60, how about the last 3 days. thanks

I am leaning toward the dry hatch method. It's not really dry.. just dryer. I keep mine around 25 to 30% during first 18 days. Then up to 70 on lockdown.
Here is a link to an article on this site that I found helpful.

Days 1-18 - 40-50 %
Days 18-Till you have chicks - 60-70 %


Some people have better luck with lower humidity, others with higher.
