I have 12 three week old chicks. They will be around seven months old come November. I live in Massachusetts so winters can get very cold and snowy. Keeping my chickens warm, cozy and healthy during the harsh winter months is my main concern. Please give me lots of advise, so I can do things right and keep my chicks comfortable and safe for the winter months. I'm a real worry wart, and I really don't want this whole experience to be stressing. I love my chickens so much already and I'm keeping them as pets.
