So I have seen pictures of the hovabator 1602n on with eggs and in pictures i have seen both red venty things in it while incubation. I have been told to take one of them out during the incubation process... Is this True? like had 1 red out during the 21 days or only take 1 out during the lockdown? i bought a steak thermometer today... this is my set up right now. it is still air... no fan. is this right or wrong? should i have taken one of the red things out?
