9 month Rooster is showing signs of aggression

[Mayflower09]

Hi all!
My 9 month old rooster is showing signs of aggression towards me. It’ll be sudden or when I have my back turned. He has 6 ladies that he’s a total gentleman for. I have more younger chicks in the nursery still and aren’t ready to be introduced. He is a Rhode Island/ Buff Orpington mix. Should I get rid of him? Or is this just a hormonal stage? I’ve never had troubles with any of our past roosters. He was hand raised since a baby.

Cull him, he's unlikely to get worse. Hand raising can often encourage aggressive behavior in birds that are prone to it.
