I have had many roosters, and none have been mean. Right now I have 3 serama roos, a LF blue marans, bantam blue salmon faverolle who is the nicest boy ever, and 2 polish roos. The polish roos are happy to be on the ground and in their own space, which is fine. When I need to get them they don't try to hurt me at all, and they are nice to the ladies. my marans roo, Big Blue, is funny. He will follow me around looking for goodies, then give them all to the girls. He is very good at his job and if he gets carried away trying to impress one of the girls, I'll scoop him up, and he just looks at me like "what the heck just happened??!!" It's the most confused look a chicken can give
My seramas... I ADORE them! Sunny is just a love bug & as nice to the girls as you could ever want a roo to be. He will follow us around outside looking for treats & to be cuddled up under my coat - WHAT!? No, he is not spoiled at all!!
My other 2 roos are nice, but not the lap chickens Sunny is. Peep-eep (salmon faverolle) loves his chin rubs. He will fall asleep if I start giving him a chin rub.
I do have 2 other bantam salmon favs (1 blue the other black), and they are both really nice also. They are still young birds, but I have no doubt they will stay friendly.
