well i FINALLY moved up from my little giant forced air with turner to a 1588 genesis with the same turner. Now with the little giant it had 2 red plugs..the top and the bottom. The top plug where my fan was at really controlled the temp and humidity when i took it out. Some times to get to get the perfect temps and readings i would take the top plug out and cover half the hole with tape so i could get good oxygen flow without losing my 99.5. My question is, during the incubator process, do i just leave the plug in? Same with hatching to hold my humidity? To me my Genesis seems WAY more air tight when closed than my old little giant, so it kinda makes me think the eggs will not get the right ammount of fresh air/oxygen during the incubation and "hopeful" hatch period. Or am i just being silly and over thinking it? thanks
