There are some breeds/strains that are predisposed to being nice, or not, but there is also an individual bird element. It is a numbers game, if you raise enough, you will get some of each. I generally eliminate the bad apples ASAP, but I have 2 now that I have to tolerate because they aren't replaceable (yet). Their sons are growing out and I doubt either one will be alive a year from now. They seem to understand their current status, that they are untouchable, but they don't get how fast that could change in the future.I'm with you LadyBehir, we love our roosters and we have 5 of them in 3 different coops. 'Cuddliness' varies but all are very respectful and come right up to us searching for attention or treats to share with their harems.... but with that being said we have also butchered off a few over the years who were raised the same way and were nasty to other flock members or the dogs and challenged us.
It is worth it to keep trying though, once you have a good rooster you really come to appreciate all they can be.
I think it's important not to be afraid of any of our birds. I can handle these 2. The one is a bantam Ameraucana, and his effort are not painful, more comical really. The other is a big guy and he is becoming more cautious around me because I have started grabbing and holding him in a way that forces submission, so he's getting smarter. I've had some in the past that were not only mean, but also "dumb as a post" (2 silkie roos come to mind). Those are worth getting rid of quickly, you don't need that combo in your next generation.
