I have a four month old chicken and she keeps attacking me out of no where. Every time I turn my back to her she runs at me and pecks me on the back of the leg. Once time she even left a mark from this. She also clawed at me one before. I have picked her up a few times but she still continues to attack. A few of my other hens have pecked me before but they stopped as soon as I picked them up. This chick is a hybrid, I incubated and raised her myself but now the only time she will come near me to attack. All my other hens come up to me when I go outside and they eat out of my hand but this one chick wont come near me at all. Ive tried calling her when I have food but it doesn't work. What should I do?
