What to do with red vent covers

[juliasflock]

So, I’m very new to incubating. I purchased a used 1602n with a fan kit. Do I leave the red vent covers in during the whole incubation process? Would that help stabilize my humidity? Thank you!

Hello. I have an Little Giant still air incubator - Instructions say from day 1 to 18 remove top vent cover, day 18 through hatch remove both vent covers. Perhaps you can find instructions for your particular model online.
