What can you actually do about ventilation besides pulling out the plugs.?If you are in lockdown I thought that you weren't supposed to be lifting up the cover. I heard one person say that they elevated the sides slightly with tooth picks so that fresh air could come in horizontally. Would you leave it like that all of the time. I have 4 serama eggs developing and I really don't want to screw up my hatch. I have a LG forced air. What about putting the bator up on blocks so that the small holes in the bottom let air in?
