I put my eggs in the incubator the morning of 5/24. Day 18 (lock down) would be 6/10 correct? I'm using a foam Hovabator 1602N. What would be the best humidity level for lock down? Should I keep the red plugs in or take them out? I was up all night researching past BYC articles and after having a horrible nightmare last night that my chicks were drowning in the eggs I'm a nervous wreck.
