I have a 4 year old Rhode Island Red who I brought indoors after my flock was attacked by a fox. She is the only grown chicken left. I didn't want to put her back outside by herself in an unsafe pen. We ordered 4 baby chickens so she won't be alone, but they are far from being fully grown. She has been inside the house for about a week now, in a large pen at night and we let her walk around the house during the day. Her face is getting pale, and her comb is drooping over the left side of her head more than it was before. I don't know if I'm giving her the right amount of nutrients or vitamins she needs to stay healthy. I don't want her to get sick. Does anyone know what special nutrients indoor chickens need?
