Quote: I incubate at 40% and for the last two hatches it was perfect. I am using the humidity pump. It has a tank and a hose the moves water to a paper thing in the incubator the disperses the moisture.
Happy Chooks does not add any water at all until lockdown, which for me would be about 15% humidity. In the past when I went that low the chicks did not absorb the yolk--symptom of too low of humidity.
Get the humidity pump if you want to only open up the incubator to candle and add more eggs.
I had to laugh at this comment....I'm thinking, of course I want to candle and add more eggs!
