Humidity goes up as each chick hatches?

Am I to worry that the humidity is above where I want it to be. We were doing great until these little guys started to hatch, and as they do humidity levels go up. Right now we are sitting at 64-65% and only 5/28 have hatched. Day 20

I wouldn't worry about that humidity, my hatches do the same thing. Sometimes it goes above 80% if I have a lot newly hatched at the same time. Ironically, those are my best hatches at 95-100% hatch rate. I add enough water to reach approx 60-65% and then just let it be. Once the chicks dry off the humidity will come back down to where you want it.

great thanks....
