I am new to owning chickens, and the people that I got my chickens from used supplemental heating with a red light. I Have kept the light because that is what the previous owners have done. I would really like to try and get rid of it. I am just not sure, with it being the middle of winter, if that is a good idea or not. I would really appreciate if someone with more knowledge on the subject could help me out. Thanks! I am so excited to be a new member to the backyardchicken community!
