We currently have seven chickens living in this 25 by 10-foot space. At night they all go into the 10 by 6-foot pen and huddle together in the dog house and we close them in until morning to protect from predators. Is this enough room? How many chickens could we fit in here if they were to have chicks? Also, they lay their eggs in the dog house/where they sleep and I read that this is not a good habit? They do have nesting boxes that sit beside the dog house inside the dog run/coop, which they perch on, but have never laid in. If this is bad, how do we dissuade them? Thank you for any and all answers!
