I have a springfield humidity moniter, and I am on day 19 with my chicken eggs due this friday. The moniter says 88%. I have both vents open, and I only have the 2 sections filled like the hovabator 1602n manual says. Last time I hatched, I filled up all of the sections and was at 65%. The chicks shouldnt drown or anything, right? Ive never had it this high, except for ducks. Maybe I will air out the room, to try and get some humidity out of the air.
