Thanks for sharing your ordeals and successes; the learning curve is often hard for us to admit. We have been raising chickens for 4 years and still learn. We have had (past tense) a few great roosters--lost to protecting the hens in different predator situations. Each one of them was very distinct, but friendly with humans and only cared about the girls. Guess we have been lucky. Last year we got 25 Brahma chicks to add to our flock, and 15 turned out to be roosters! Since they are a dual purpose breed, we had no problem raising them in a separate coop/free-range area until the fateful day came.
One little rooster, a red one, would not compete with the other rooster games. They were busy all day chasing and fluffing and eating and making lots of noise! But the little red and gold rooster should have been named Houdini, because he would somehow escape into the goat pasture, scale another fence, and be back with the hens in their pasture about every 20 minutes after I caught him and put him back in the boy pen. He wasn't hurting anyone, he just wanted to be with the girls. We decided to let him stay on when the other 14 went to the freezer. We have not regretted keeping Rooty for one minute! He is only interested in the hens, protecting them while free ranging, pointing out tidbits of food, and making all of the many vocalizations I have learned to understand as warnings and come hither noises. Rooty comes when called out or to go in at night, but doesn't care about humans at all.
Roosters get a bad name. Some are the best. You don't really need one, but we like them. I hope Rooty stays with us longer than the last ones. We have improved fences around free range areas to do our part. He obviously can't do it all by his little self, even if he is a big Brahma Boy!
