Vicker - take a good look at your coop/run. Do you have hideouts, escape routes, roosts and multiple feeders? That can really help chicken society.
However, the crowing if he is close to your house can be a problem. Mine is over 100 yards away, so the noise is easy to ignore. I would not like it close to the house.
Mrs. K, they have plenty of space for them to get away from each other. I have a very large area on our acreage that's fenced off for them and let them out to free range in the evenings. After I decided to give this rooster a chance, we came home to a buff with a lot of blood on her head. He was just too aggressive in his mating. He didn't do the little dance to see if they were interested. He just pounced. The buffs didn't resist, but he still held a firm grip on the comb or back of the head. I plan to build a separate coop and run to limit mating time with the next rooster if I end up with another one. I used to have a flock of Black Sumatra's. There were at least 3 roosters that never fought, never hurt the hens, and actually tried to protect the flock. Every breed of rooster since then has not protected them and has been solely focused on mating as soon as his feet hit the ground in the morning. The Sumatra's were just a small breed that laid small eggs, so I moved on to other breeds.
