I've said it a hundred times before, and I'll say it a hundred more times to come.
You'll find conflicting answers on this subject - some representing the group that treats their cockerels with profuse affection, and others preferring to adopt a hands-off attitude. Both sides claim it's worked for them. What does this tell you?
It has very little to do with the method in which young roos are raised, instead based upon individual tendencies.....at least, in my opinion. I have experimented with both methods, and neither resulted solidly in good-natured (or bad) roosters. My last group of 6 OEGB cockerels was cuddled flat, to put it lightly. All received the same amount of love. Three became human-aggressive, two are standoffish (but completely lack aggressive qualities), and the last is as affectionate as one could hope for.
Might I suggest doing what you feel most comfortable with? Either way, it's likely your boy will turn out exactly how he's going to turn out, regardless.
Most of all, enjoy him if you wish to!
