A few months ago I received an opportunity to receive two free chickens. Who could pass on that opportunity right? These birds were the calmest and most docile birds I have ever seen. They were from family down the road and I knew that that they did not have anything wrong with them. So I loaded them up and brought them home with me. Everything was fine while everybody was out in the yard. The dominate hen a black sexlink did not mind them. The rooster a silver phoenix acted like he was interested but was very sweet at the same time. And our other hen a golden sebright was fine until we put the new hens in the run that is attached to the roost. There it was like one of them said something to insult the other sebright and it was on. The jumped on her and started ripping out feathers and going for eyes and such. Seconds later the rooster got involved. Of course I was not going to sit there and allow this to happen to a defenseless bird as she just laid there. I do not want to introduce another adult bird to the flock. But I want more chickens as I donate extra eggs to people in the church. If I get some more hens this spring will I have an issue. I know the dominate hen is very mothering as she took the rooster and hen that I have know under her wing since she was the only one left after an attack by most likely a coyote. If the rooster keeps attacking my wife and the sebright won't accept another bird we might not have to worry about it soon. I would be open to any and all suggestions. Sorry if this has been asked before.
