So I have 2 seep rate flocks. 1 flock of 6 is 1 1/2 years old the other flock is 5 months old. They have been separated but not next to each other. I built a new coop and run and I'm wondering if they r all going to the new coop do I still have to separate them or can I put them all in together. Where as there won't have been any pecking order yet. It is a new coop for all of them. It is 16x8 and the run is also 16x8.
