I have a roo that is outside and full sized, my chickens have free run of the back part of the yard w/ the garden and fruit trees, so I walk amongst them daily and dig and garden w/ them, so can not have an aggressive roo. My boy Oreo was hand raised also and was a great boy but went through a spell at about 2 years old when he started attacking me, the only thing that saved his life was I had not bought my pellet gun yet (I have one now) I tried the hitting him that just instigated more aggressive behavior (I thought I killed him once he was very lethargic for a couple of days) anyway out of despiration one day he came at me and I had the water hose I turned it to "jet" setting and "water boarded" him I was aiming for the head actually trying to drown him I was so angry, that whole day anytime he got w/i hose range or even looked at me I sprayed w/ the jet setting as close to the head as I could and continued spraying until he was out of hose range. He has never attacked me again.
