Every single day, there is one same Buff Orpington hen that pecks my leg or boots, then squats expectantly. I have tried saying "no," in all different kinds of voices- mad, kindly, etc. I have tried pushing her away. I have tried ignoring her. I have tried shouting at the top of my lungs, "stop!!!!!!" I have tried petting her on the neck like I do the other hens when they squat in front of me, and saying, "Hi Gurdy!" How do I stop this behavior? Nothing seems to work. It hurts when she pecks me.
