I have to totally disagree with you Miss Prissy.
I have been flogged repeatedly by various roosters and have the scars to prove it, one less than an inch from my left eye. I still have those same roosters and haven't been touched by them for years despite the fact I'm in with them everyday.
Roosters are not untrainable. I know, I have 8 well trained roosters. Only one is truly docile from birth, the others are normal roostery roosters. I handle agression immediately in the younger ones so it never escalates to biting or spurring like when I was first learning to handle them.
I can do anything with them, they respect me, BUT they don't respond the same way to anyone else. In that way they are very different from dogs and no amount of training can help that.
In no circumstance should young childern be trusted with roosters or hens for that matter, there's just too much potential for serious permanant harm. Again no training will change that.
If you want a cuddly pet rooster you should definately get a docile breed, cochins, orpingtons and the like are wonderful for that. Bantams are great too, and so adorable!
Good luck with your pet search!
Edit to add: You can have more than one rooster in a pen if you have enough hens. It won't work in every single circumstance some guys just don't get along. But it's not impossible or even rare for two or more roosters to co-exist in a flock and team up to care for the girls. My boys will keep a joint eye on the hens and split up if the flock gets too spread out.
Some of the roosters grew up together, others were stangers but all but 2 of the 8 get along. The fights were short and no more bloody than a hen fight.
