My daughter came in from out of state for a visit. The last time she was here, Gladis, my rooster was just a young one. (Yeah, Gladis... We only assumed he was a she being there was only a 1% chance she would be a he so...) Now that he is around the 6 month old age, full grown, mating everything in site like many of us guys attempted to be at the adolescent age of 16 he suddenly attacked someone for the first time ever. We get people here as friends may come by to visit so he is no stranger to strangers. My daughter, on the other hand, he despises!!! He will hunt her down, act nonchalant while pecking at the concrete or lawn, getting closer and closer until he feels close enough to attack. No blood. (yet). Going for her tatoo'd leg. We covered the tattoo to see if it made any difference but didn't help. The two of us (Gladis and I) have had our "moment" of dominance. I've won that competition. As I see him walking toward my daughter, I intervene as he quickly retreats to where he was prior. What in the world could be on his mind with being so aggressive toward this one person and no one else? Has anyone else had this kind of behavior? I've heard of "one person" animals but that is usually for love, not hate.
