My absolute worst was a Delaware Roo that went blind for some reason. If he realized you where a person he was fine (if not a little afraid from the punting's brought about from the blind attaching), but if you just walked up to him and didnt say anything he wold attack full force biting and clawing. He did not forage and peck at the gravel as much as the others so his beak grew to a very fine sharp point, I reached down to pick something up in front of him one day and he got the back of my hand and began twisting his head as he clamped down, he sunk the little point in and twisted slashing me open a lot worse than I EVER thought a chicken could, I am not a wienie, but I was considering going and having a couple of stitches put in. I let that little $#%^# survive in spite of his attacks because I felt sorry for him, but was silently relieved when he passed from an illness my flock contracted last fall.
The rest of my Delaware roos where fine toward people, and amazingly toward each other, but VERY hard on the hens (Savage gang mating).
The Alstralorp Roos I had seemed to grow bigger, faster than the delawares, and where FAR more aggressive toward each other. They where not Super aggressive toward me but they did bite me a time or two.
