For a good laugh
That is how my first flock of chickens treated cats....my poor Lucia was so traumatised she still won't go out if she can see a chicken.
That was funny! My Sebastopol goose used to jump between fighting roosters like that, but then I had to re-home him because he started being difficult with the hens. I wonder if they see it as a hierarchy - that chickens are above rabbits? The rabbits sure didn't put up a fuss!
