I had 6 hens and 3 died suddenly in October. Since then, the pecking order changed. One of my hens, who is now the leader, is very aggressive toward me. The other two hens squat for me to pet them, or even hold them and when I pet either one, the meanie attacks me with her feet and/or bites me to the point of drawing blood. I have 7 babies that will be integrated in about 3-4 weeks and I’m afraid she will hurt them too. How do I get her to stop attacking me and will she be aggressive toward the new comers??
