We have 2 -10 week old chicks. So far everything seems to be doing well. But I have a few questions. We live in N. Idaho and are due for winter weather for the next 4 months. I also have 4 hens. So my questions are. When should I change their feed to grower feed? When can I put them in the chicken coop? When will they start laying since it is so cold? What is egg bound? I currently have them in their own pen inside the shed with a red heat lamp on to keep them warm. Even when it is 30 degrees outside their pen is 60 degrees or more. Any suggestions?
