Just some info for you new hatchers--------I know some like to take the time to draw air cell lines around the eggs---and thats fine---its your incubator. I do not do that, never have----I do not feel its needed. When I candle my eggs on day 12---I can see the air cell, when I candle again on day 18, I can see it again and I can see if it has gotten bigger. I feel if you get the humidity in range, the air cell will do what its suppose to do. Humidity in my area is probably different than in your area----so how much water I use is probably different than what you need to use--------also if your incubator is in a room that has controlled temp----it would be different than someone that has theirs in a uncontrolled room. I have hatched 1000's of eggs in a indoor controlled room and 1000's in a outdoor uncontrolled room with 95 to 100% hatch rate on fertile eggs, BUT the outdoor/uncontrolled room I have to monitor the humidity of the room and and in the incubator---adjust as needed as well as do things like wrapping the incubator when its cold(can not block vent holes) or opening the room up when its hot to help keep the heat/temp in range. Doing what is needed to keep the incubator readings in check/range is what's important. Good Luck with your hatches.
