I had begun to introduce the two groups of youngsters on my patio (two different age groups). All went pretty good, except for the cockerels. The cockerels will NOT be combined into one group. I took the oldest ones to the grow out pen in the coop. They are adjusting well. The younger group is still on my patio, and I moved them into the bigger cage. Yesterday, when I went to let them out to have some patio time, the cockerel would not let the pullets come out of the cage. I sat in a chair, and watched. He was enjoying roaming the patio, looking for treats (mealworms), but every time the pullets would try to venture out, he would chase them back in. I got a handful of mealworms, and called the gals to come get them. The little cockerel came charging at me from the other side of the patio, jumping like he jumps on the girls, hackles. When I first saw it, I though something had spooked him. When I realized he was mad at me for calling the girls out, and coming after me, I stood up grabbed him, and picked him up. I held him for a bit, put him down, and made him submit, then let him go. By now, the pullets are out on the patio too. He kept herding them away from me into a corner, and standing between me, and them. I went to pick him up, to put him back in the cage, so the gals could enjoy patio time, when he turned around, squawked at me, and tried to peck me. I made him submit, and picked him up. When he wanted down, I kept holding him. When I was ready, I put him down, and made him submit again. No more problems. The little stinker!
