Yes, roosters could be really aggressive. One of my earliest memories is sitting on Grama’s back porch eating watermelon one summer day and the rooster attacked me and spurred me. I was screaming and crying and Grama came flying out the back door and beat him off with her broom. The next day we had chicken and dumplings and it was so good.
Those spurs are no joke. Guy I work with raises chickens and got spurred by his rooster right through his heavy leather boot and into his ankle. He said his sock was soaked with blood. His wife asked him to kill the rooster because she was worried he’d attack their young children. So, like many of these stories the final scene was a nice meal.
