Humidity in incubator too high

[Urbanflockontheblock]

First time incubating, first time posting here;
My "Little Train" 8egg incubator doesn't seem to have any vents. It has big windows, and a bottom tray for water, but today (the first day with eggs) the humidity is steady in the 70s. I dont know how to fix this without vents.
Any tips or experience with this issue?

Lift the tray of eggs out and using paper towels or a clean sponge, mop out some of the water. You'll figure out when to add, then just do a little. Humidity is an average, but you don't want it to be in the 70s for too long. You'll want to average it out around 45-50% until lockdown, then 70% is good.
