I have 4 one year old hens. Had 7 but a dog killed 3 of them back in April. I purchased 4 one day old chicks and now they are 16 weeks old. They are keep in two separate coops. The young ones coop is one of those "Chickens in a Hutch" and they are now out growing it. The are intimidated by the older hens. If they get within a foot or so of each other the older hen chase the young one. My question is how can I get they to become one flock. They and I need them to roost in the same coop and run. Please advise me. Thanks to all. PS. An added correction that I forgot to mention. "They all free range at the same time. But they keep them selves seperate for the older hens. The babies have been free ranging since they were 2 weeks old.
