Many, many folks are doing dry incubation, which really isn't dry. My goal is to run at 30 - 40% humidity through day 18, then increase to 65%. Your humidity through the first 18 days is managed to achieve the appropriate air cell size to match the charts. I recommend that you read all of this excellent compilation of hatching information before plugging in an incubator!!! It will greatly improve your hatching success if you read and follow the advice that it contains.
You're very welcome. Happy hatching. Most important advice: calibrate your thermometer and hygrometer, be sure that your bator has been up and running with stable temps for several days before setting eggs. Be prepared for temp to drop when you put the eggs in. Don't change that setting... just leave it be unless you get a temp spike. Then adjust if needed after the first 24 hours. Also, before setting eggs, check for warm and cool spots in the bator by moving your thermometer throughout the box and checking all spots. Even with a fan, you're going to find some variation.
