I am currently on day 18 with my incubation and i just realized i didnt know what to do with the plastic red vent plugs? When do i take them out? Do i need to take them out? What is the purpose of them? How many do i take out?
Do you have a humidity moniter in the incubator? I usually keep them closed until all the chicks hatch. Then I remove them. Or if the humidity starts to jump when they start hatching and gets too high, I'll pull one plug out.
My Little Giants have/had 2 red plugs on the top. I pulled them out right off and I've never closed any of those vent holes during incubation or hatching.
When / if you remove them, your temperature and humidity may drop, and need to be readjusted.
