Of my 4 Cochin bantam cockerels, only 1 (Smokey) is the best. I'm keeping his sidekick, a 2nd in command.
He is very attentive to his ladies, he follows them around while they peck and forage, and he stands guard over them, watching and waiting. He hardly ever gets rough with them, wooing them gently and patiently. When I come out with oats and treats, he calls them and everyone runs to me, but he doesn't start eating, instead he watches politely and waits till the ladies have enough and then he starts eating.
I'm culling 2 of my cochin bantam roos, selling them off on Craigslist, because they bully the hens and draw blood out of each other. Yesterday was the final straw, because they drew blood on one another's combs and wattles, and I had to take them in, clean their wounds, and keep them in chicken hospital (our house) for recuperation. Nothing wrong with taking care of them, but I really don't want any major fights in my flock, the blood can stimulate more bad behavior in the rest of the flock, and to maintain peace and order, those who don't agree to the rules will just have to go.
