Thank you all for the well wishes on poor Harris. What a terrible way to go! Someone has very kindly offered to "take care" of the mean rooster. It will be a huge relief to see him go. The whole thing has made me worry for Heiser since I have a young dark cornish/CCL rooster that has grown up in the mixed flock under Heiser (I combined the two flocks for winter when the young boy was super young). I worry he might decide to challenge Heiser and I can't stand the thought of something like this happening to my gorgeous sweet Bielie boy! Should I be concerned or was this a fluke? Has anyone had anything like this happen before between roosters? Is this sort of extreme violence normal?
