We had a Wyandotte rooster in a coop with a run and his four wives. He was another that was really nasty. He would get up in the tree when he was in a bigger pane and fly at you, attacking from above so, he stayed in a coop.
I wanted to collect the eggs and to do this someone would stand by the run so he was trying to attack them and I would grab the eggs.
This particular day he didn't come outside to attack. I slowly opened the egg box hatch expecting him to have got wise to our antics. He didn't appear. I got down on my knees by the run and peep inside to see he was dead on the floor.
None of us mourned him.
