If you can find fertilized eggs locally you'll get a better hatch than if you have them shipped to you. 100 degrees and about 35% humidity for the first 18 days, then 100 degrees and about 65% humidity for the last 3 days (21 days total). They need to be turned (3 times a day by hand or with an automatic turner) foro the first 18 days, then laid on their sides and not turned for the last 3 days. Have fun!
