I don't have the plug out, should I have it out? I don't know how I would keep the humidity up with it out. I put the cloth right along the side so I can get to it with barely opening the lid. Thank you for your advice it has been really helpful.
I'm not sure how many eggs you have in there right now.. but the hatching eggs will need oxygen... so I always recommend that the vents be open
I would much rather have a lower humidity than dead chicks from carbon dioxide poisoning
