My local feed store, here on the Big Island, has just sent in the order for chicks. So, I should be getting my 9 chicks (2 Buff Orpington, 2 RIR, 2 Barred Rock, 2 Ameraucana, and one Barnevelder Roo) soon. I have some questions about brooders. The temp at my house is around 80 daytime and 70 at night. How much heat do these chicks need? How big a brooder do I need to make? How soon can I move them into my almost finished coop?
