My Australorp went broody for the first time. How are they with hatching eggs? Will she stay put? Do you have to put food and water right near by the hen when broody or will she on occasion hop down and get food and water? She is sitting in a nest box inside the coop....there 4 other hens and a rooster. Do I need to separate her? Will other hens or a rooster kill newly hatched chicks? Thank you.
