I am 68 years old. I raised chickens for years but quit about 15 years ago. I have now started back with about 50 laying chicks
What does the humidity need to be in a still air incubator for first 18 days and last 3?

In a still air or circulating air, the relative humidity doesn't matter. However, it depends on whether you're doing a dry incubation or not. You can allow your incubator's humidity to drop down to 28% (but NO more) without any problems (this is considered a dry incubation, because you're not adding water as frequently), but no more than 55% for the first 18 days. After lockdown, you need to boost it to at least 65%, preferably 70%.
