I have a young big Buff hen ( 23 wks, hasn't laid her first egg yet, but two of her flock have started laying. ) who is the flock leader. She almost seems to get jealous when I hold and pet any of the other 5 hens I have. They are all the same age, raised together since 1 and 2 weeks old. When I pet the others she comes in to peck them, ( they are free ranging ) so I try to shoo her away. All this does is get her mad, and she won't back off. I have pushed her away, but you can see her eyes are fixed on whatever chicken I have on my lap. She can be far away, see that I have one or two on my lap that I am petting and she comes in for the attack. She walks over, I try to shoo her away, then push her away and still she keeps coming. This time she actually pecked my finger and drew blood! Then I shoved her away hard, and she left. What is going on with her?
