I have my incubator set up with my eggs in it in a smaller spare bedroom. I just put them in there yesterday evening and I've been closely monitoring just because my incubator hasn't been used in a while, been through two moves and want to make sure everything remains functional. So anyway, I keep that door closed at all times but notice when I open the door there is an immediate .2-.3 temperature change?! Should I be worried? Reason why I chose this room because my only other option was another spare bedroom near my laundry room with furnace included in that room so constant temperature flunctuations I knew wasn't good and wanted a room where no one uses. Would you just leave the door open to the room that the incubator is in now at all times so it's more consistent or? Doesn't help we have floor fans going through the house either. I'm trying dry incubation method right now as well and it's staying between 25-33% so far, do you all add a teaspoon of water if it gets below 25%? If yes/no, why or why not? Thanks!!
