you guys are funny!!
Like mentioned before do not let your guard down for a second when you go in there to collect eggs or work....he will challenge you again, for now you won the battle.
the lady ont he next street over has many chickens and several roosters, ok when I say lots I mean she has a flock of about 400, anyhow she has a straw broom handy and the first time a roo challenges her she uses it, not to hit him, but shoo him away, she told me that when the roo tried to challenge her she sweeps it at the roo and they don't like it, after several encounters they usually know to knock it off. She told me she barely ever has issues, the only issues only arise with a new roo she hatched that is coming of age. I am trying to get a roo from her and I did ask her how she keeps her roos so docile, she laughed, said that once they meet mr. broom they behave quite well. lol....
She only ever encountered one roo that would not give up, and was picking fights with other flock members and including a goose. She didn't want to re-home him because he was aggressive so she turned him into soup...
