Welcome to BYC! Glad you decided to join our flock. Kelsie2290 has given you a good link for answering your questions. There is also a good article on Winter Proffing Your Coop at
https://www.backyardchickens.com/a/winter-proofing-your-coop-why-and-how. You have some really good breeds. Black Australorps are my favorite standard breed. I have raised them for years and they are extremely hardy, very calm and gentle, and excellent layers of large, brown eggs. And the Red Sex Links (Red Stars) are egg laying machines. Please feel free to ask any other questions you may have. We are here to help in any way we can. Good luck in getting your coop ready for winter.
