I have a chicken that I have had since March of 2016. She has recently started to attack me when I go into the back yard. She runs after me and pecks at my legs. I put my foot up to stop her one time and her feathers all stood up and she went a little crazy on my shoe. How do I stop this behavior? She has never been very friendly, does not let me hold or pet her, and just started eating out of my hand. She is a different breed from my orpingtons so I dont know if it a breed thing. This hen is more aggressive than my rooster.
