I am on day 11 and my humidity has been a consistent 35% today it dropped to 25 so I added a little water and its up to 45%. Should I try to get it back down or leave it and what is the highest it should be at this point...Thanks!

Humidity is relative to air flow - is your incubator totally sealed with little air flow? or are there vents that are open?

Really - low or high humidity for a day or two shouldn't harm anything - remember the hen gets up at least 1x per day & humidity drops to ambient when she does that - so variation is OK.

Having a high humidity for the duration of the hatch will have many of the chicks drown when they pip - they must switch from breathing through the shell via the membrane to breathing air - while still inside the egg. Too wet in there & they dont have air to breathe.

That said - you are probably fine - I run my incubator at a higher humidity - but I have a lot of air turnover.
