I had a RIR roo that wasn't nasty, but I kept him intimidated once he became grown. However, he did tear up a couple of my hens' backs. They both had no feathers and fairly signigicant skin tears that required doctoring. I had 11 hens so it wasn't due to not enough hens. He did protect them and settled hen squabbles and led them all over the property to forage once I let them out of the run, but it wasn't worth it to me to have to deal with treating skin tears on my hens, so I killed him and ate him. I do intend to have another rooster this spring, but I will have a separate 'bachelor pad' pen to put him in when he gets too 'amorous' with the girls. They are neat to have and are so pretty, but you need a separate place to keep them sometimes. I have RIR's and Buff O's. Only a couple of the RIR hens are friendly, but they all come running to me when I go outside because they know I bring treats. Welcome, and have fun with your chickens.
