Welcome to BYC! Glad you decided to join our flock. If you run into any problems don't hesitate to post on our Incubating and Hatching Eggs section at https://www.backyardchickens.com/f/5/incubating-hatching-eggs. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with hatch.
Sorry I have never used an incubator but, more responders should be coming on that can assist you.
Meanwhile go to the forum spot above, then hover over "Raising Backyard Chickens," The menu will open to the right side with incubating and hatching eggs, etc.. You can continue on to more information. This should give you some help.
