Yes, you got my idea on the fans, One for moving or increasing humidity and others for moving the air. Easy to get too much air movement, as this is a hatcher, avoiding too much drying of the eggs once externally pipped is a key factor. Guess I'm trying to say, up the humidity but not have air moving so fast a plane could take off.
Maybe build like each draw is an individual hatcher . . . . the expense adds up in electronics though.
Sealing up-- when building our house we sealed EVERY nook and cranny, then we put the holes for ventilation where we wanted them. Warm air flows upward. = in vents low, outvents high. Maybe drill hole as the invents. That's what I did in my cooler bator, and then used tape to cover a few as needed. A balancing act; one where more is better with the high capcity of this hatcher. IT needs a name. lol
