We've finished our coop and are ready to move our girls from the garage. I have two groups one at almost 8 weeks and one at almost 5 weeks. They have been sleeping in separate brooders but spending the day together outside in the run. Any advise on transitioning them to sleeping together in the new coop. also are the little ones ok at this stage to go outside. They say it will be 60 degrees here on the cape tonight? Is it ok to leave the roof vents open for ventilation? Should I leave the windows open too? One of the bigger girls has been picking and the younger ones when in the run. No injuries thankfully, she just tends to chase them and peck now and then. Should I be worried about locking them in the coop together at night. All advise appreciated.
