Oh wow ..... Oh noooooo....... I can't hardly see those dumb air sacs. I don't think they are that big as on that picture....you have a fan model right? ok, I want to make sure your gonna have a good hatch so I will ask that you take a minute to read this..... ok maybe 2 minutes.... then ask questions! ITS IMPORTANT TO KNOW THAT YOUR AIR CELLS ARE CORRECT WHICH MEANS YOUR CLOSE TO WEIGHT LOSS GOALS! https://www.backyardchickens.com/a/hatching-eggs-101[SIZE=22pt]Humidity is [COLOR=FF0000]NOT A SET NUMBER,[/COLOR] you need it YES![/SIZE][SIZE=22pt]However, you use it to "adjust" egg weight loss during incubation.

THIS IS YOUR GOAL!! You can monitor this by marking Air cells and also by weighing.

You begin by [SIZE=22pt]ONLY adding a small amount of water and keep Humidity between 28%-45% and adjusting as you weigh or candle depending on moisture loss. So if your air cells look too large you must add humidity, too small lower it, and if your weighing you adjust as needed.

Do your best to keep the humidity level in the incubating room around 50%. You may actually need to dehumidify. By controlling the room humidity, you can be more accurate with humidity inside the incubator. Just remember high humidity is MUCH worse than low humidity as higher humidity hinders the evaporation inside of the egg.
