Peacock is becoming aggressive

[Riverrunhenhouse]

My 3 years old Indian Blue peacock suddenly became aggressive only to my 25 year old son. The peacock roams freely with the chickens and 2 rooster and at night loves to roost in the highest tree we have. He has never been aggressive until now. He hears my son come out of the house and he runs to him and attacks him. When my son tries to leave in his car, he attacks the car too. Could it be because of mating season? I don't have a peahen for him yet, but in 5 months I will have 2 for him. Does anyone have experience with this? I don't want anyone to show aggression to the peacock but he scratched up my son pretty bad. He doesn't bother me, my daughter or my 86 year old dad, only my 25 year old son.

My Peacock Jack was a jerk last year. So I would catch him in the net if he was bothering me or my youngest son. After a while if he even saw the net he would take off running away from us. This year he's been penned up and hasn't yet been aggressive.
We got something like this in the fishing area at wal-mart last year.
