Re: birds and rape, wait til you see ducks...
I should note that there are roosters and then there are roosters. We had a really amazing one, a well bred barred rock who was a real gentleman. They have an important role in the flock, warning about and fending off predators. He died after sustaining wounds from diverting a fox over 100 feet away from his hens. Tussled with the fox from the coop all the way down to the road, distracting it from his hens, then hid under a passing car until we could rescue him. Miss that guy.
But it is important that the hen to rooster ratio is right, or they get competitive and mean.
