My situation is a little different; first I have had a hen inside for 3 days now recovering from lash egg. I also have a silkie roo in a separate pen but inside the coop and has been visible to the flock. I removed him from his 2 hens 3 days ago because he was overly aggressive with them. He is a lot bigger than the hens. Can I add him to the leghorns and red sex links? If I add him and the inside leghorn at the same time will that ease both of them from the reintegrating process? anyone have a better idea? I should also mention I don't have the room to make a separate pen for the roo. this is Barney. He is quite a bit bigger than my silkie hens.
