Humidity issues

[Jay262]

Im on day 7 and my humidity has spiked to 65 and 70 i cant seem to get it down. If i drain most of the water it drops to like 10 percent humidity if i add just a little it spikes back up to 70. There seems to be no in between no matter how hard i try. I have used this incubator to hatch ducks and chickens many times before with no issue. Its a havbator any ideas on how i can controll the humidty? Also will high humidity at this stage being 7 days kill any embryos?

I used thin card board or heavy paper strips to cover part of the water canals in my hovabator. A humidity spike won't hurt the eggs but you don't want to leave it up there because the air cells won't get big enough for the chick to hatch and it will drowned.
