Randal Is Correct From My Experience They Will Hatch Better With Higher Humidities. Now I Have Found Anything In The High 80's And You Will Be Drying Them In The Brooder As It Takes Forever For Them To Fluff Up At That Moisture Level.. I Routinely Keep My Hatcher In The High 70's But I Also Hatch Upright To Help Prevent Drownings Enutero. Thats Just My Way And The Best Way I Have Found That Works Here For Me... Hatching Is An Artform That Must Be Learned And Perfected For Each Individual Many Things Can Affect It From Your Ambient Humidity To Your Equipment. Ultimately You Must Figure Out The Best For You And Your Desires
