I have 4 hens are that are about 14 months old and they all get along great. I have two ~4 month olds I am trying to integrate. I kept the chicks in a kennel inside the run for 2 weeks and had them free ranging together for a couple hours a day. I have tried to integrate them for 2 days unsuccessfully. This morning, about 90 min past sunrise they pecked the one til her beak bled and they other hid in the top corner. They won't let either need the food or water (3 of each). It is not just one of the older girls pecking them, it's all 4. It's not a peck and run away either. The two new ones are very sweet. One is as big as the mature chickens and the other is still smaller). Having two coops or two runs is not possible. During free range time yesterday the big girls were very aggressive at the food and water stands (have 2 out). Please help!
