I have a question about keeping my chicks warm with my broody hen. I have the 5 chicks and my broody in my second coop for my younger chickens, but I have never raised baby chicks inside of that coop, I only put the younger chickens in there when they are fully feathered and can hold their own heat, I raise the chicks in the brooder with a heat lamp but want to do it the old fashion way with a broody. I am just worried about the temperature outside at the moment which is at around 40 degrees Fahrenheit at night and around 65 at night. Can my Light Brahma broody keep five, three day old chicks warm in that temperature to keep them at 90 degrees? Or should I be worried?
