Have you ever had a rooster before this one? Have you ever heard about how some roosters are aggressive to people and sometimes hurt people? I don't mean to upset you or worry you needlessly, but you need to learn to handle your cockerel and establish a relationship with him now or there could be issues with aggression later on if he gets mixed signals from you.
He can get mixed signals if you are afraid to touch him and handle him. I'm not talking about cuddles. It's not proper to cuddle a rooster. They're best left alone except to inspect them occasionally for health reasons and to discipline them. It's important you learn to manage him now.
You can begin by teaching him to come to you. This is very easy, and you can teach your hens as well. You need to choose an audible cue such as a clicker that you can get at
PetSmart for a buck. Or use a word or phrase. Then use that cue each time you offer your chickens treats. Very quickly they learn to come when you use the cue.
When your cockerel is coming to you when you signal him with the cue, next step is to hold the treat close to your body so he has to come very close to get it. Do this for a couple of days, but don't try to touch him yet. When you see he's trusting you to come in close to accept a treat, then reach out slowly and stroke his neck and throat. It's only a short step to picking him up from there.
As far as discipline goes, it's best to ignore the cockerel except for when it's necessary to handle him. He needs to understand you trust him to learn his role in the flock. If you leave him alone, except for when you need to handle him, you shouldn't have any aggression issues.
Your plan to slowly integrate him should work. The objective is to allow him to adjust to the hens without becoming overwhelmed. The special perch probably won't be necessary as he will soon be the flock favorite and the hens will all want to be the ones to roost beside him. It shouldn't take very long.
