Just went into lockdown last night at 10PM. All eggs are currently moving and with proper air sacs. Anyway, I put in a large bowl to raise the humidity BUT the only way to get it up to 60% is by making sure there is no air leakage. It's a cooler so I taped up the lid and so forth. Everything is currently stable. My issue is ventilation, I don't know how to keep good ventilation without loosing all my humidity. I did open up a small dime sized hole this morning to try and get at-least a little bit of new air in. Although, I don't think that would be enough? So the question is how important is ventilation apposed to humidity? I really don't have a way to raise humidity as all the space in the incubator is taken up and I can't install a sponge because I have the water container covered so the chicks don't fall in.
