Hello. I have a twelve week Buff Orpington Roo and two pullets . I am trying to integrate them into a flock of four older Buffs who just turned three in April. These girls have a definite pecking order and a strong lead hen. I have been trying the playpen method. I have the young ones in a grow out coop next to the older girls coop. They have been able to see each other for about a month. Fiiendly interest and pecking. No problems. Tonight I put them out to range in the paddock next to the big girls. Only plastic poultry fence in between. The older forks came to investigate and immediately got into a battle with the Roo. Bloodied combs on all sides. I separated them again and wonder what to do next. Wait longer? Just gave two separate flocks? Rehome the Roo? Any advice is aporeciated. I will NOT consider killing the Roo.
