Not this little hellcat. She goes straight for the other chickens' throats. A bossy hen comes up to investigate and Caroline flies at her in a fury. It's hard to know where the cycle of violence starts -- was she picked on as a child? did they tease her all night in the henhouse? is she just a psychotic chicken? This morning I had to break up several hen fights with the hose. Eventually the others backed C into a corner facing the wall.
Then we did what I knew we were supposed to from the start.
We put her in a cage in the middle of the yard. This way, supposedly, everyone can get used to each other without bloodshed. Whether this will actually work, I have no idea.
