Funny you mentioned that, cause 2 years ago I was selling some of my pullets to a young woman that stopped by and my dog out the blue bit her ankle and she freaked out. That has never happened before. Guess my dog hates young women.I have a 6-year granddaughter here often. I do not allow her around any of the roosters. Even if a rooster is really nice - instinct and his "rooster job" can kick in and someone can get hurt. But guess what - it is the same for dogs. No matter how long you have had a dog and let's say the dog has never been aggressive, the dog still has the capability of being aggressive if the right trigger is pushed.
