You don't want to plug any holes either when they are about to hatch because you won't get sufficient air exchange and they can suffocate.ok, so I am on day 19 trying to get this humidity perfect.... there are two plugs.... if I unplug one hole I get 74% humidity- if I unplug both holes I get 68% humidity. which is better? I have 42 eggs, majority are Marans.(if that matters).
