Rooster question..

[Henrys mom]

I bought 4 chickens at 6 weeks old. One was a Rooster. (Gus) I loved to see him develop his own "style" of crowing, it was unique to say the least. I had a co-worker who needed a home for her last remaininf beautiful black laying hen (about 3 yrs old). I brought her into the flock and she was accepted by the girls. But Gus, on the other hand, tried to kill her. REALLY. This was not a mating thing. I tried everything, but since I got chickens for the eggs, and the new hen was laying, I had to find a good home for Gus. I did, and he is doing well among a flock of Bantams!
Question is - why would this rooster attack a chicken? I mean, c'mon, she could have been a part of his "harem"
Any insights to this behavior?
Thanks!

She was an intruder to him. Violated the sanctity of his world.

Rosters can change their behavior from one day to the next ... I had 4 roos that grew up together has chicks ... they were
all getting along fine for the last 5 months until today. When I came home from work I found 3 of the roos were ganging up on, and would have probably killed the 4th roo.
