Hi! I have eggs in the nurture right 360 in my classroom. During the day I see the humidity staying steady at 53/54% but this morning I got here early and it was down to 30%! Should I worry?! I’m on day 3. Also, anyone with experience with this incubator, do you NEED to add water daily? The little A dispenser always has water in it, I don’t want to overdue it!! Thank you for any and all feedback!!!
