Quote: FWIW, mine are not usually sweet or docile when it comes to the pecking order. They DEMAND their "rightful" position at the top, and will fight for it. The smaller the silkie hen, the more likely she will demand top placement. Now they ARE sweet when it comes to interacting with people, but other birds? no way. Anyways, that is my experience.
Any time you add new birds to an existing flock, it is easier to add several than to add one. And it can be helpful to let them meet in a new place so that they do not feel that "THEIR" space has been invaded. Even just a circle of wire fencing to form a temporary pen or letting them run loose under supervision is helpful.
