I've had somewhere around 15 different roos and they all have been friendly and gentle except three, my one Wyandotte is the meanest roo I've had, I have scars from him. The 1 Buff orp is super calm and gentle but shy, all 3 of my silkie roos are teddy bears, of the 10 black australorp/bantam crosses I've had, 3 were just like dogs and and my sister's kids adored holding and playing with them, 2 of them were mean and would attack, and the rest were just fine. Can't peg personalities on breed though
Part of it is the time I spent with them when they were raised, I didn't have as much time with the Wyandotte and Buff, so that could be why one is evil and one is shy
<Take this guy right here (Zaxby), he got the occasional invitation to come in and sit on a chair and hang for a while! He was just such a character, loved people, would even fly up to anyone around's shoulder. I prefer roos to hens as far a just being pets any day.
I can't say ANY of them are particularly quiet, the bigger breeds have a lower pitch going for them though
