I have had 3 roosters in the past that were in between, they were dominant with each other and mean to each other, they weren't mean to me bc i showed them who was boss they were buff orps (one i think wasn't but looked like one only). They all got culled under different circumstances but had a nice enough life of about 6 months or so
Then I have currently a hen turned rooster buff orp, she has turned a bit mean to my daughter but is very gentle with me though she trys to corral me with that wing down, don't pass or out of my way thing
I have another buff orp rooster he is nearly 2 years old he is with my hens and he has never been mean to anyone in my family not one peck, or corral, he gets mad at my hen turned rooster when she corrals me, he is super gentle eats out of my hand, but his one rule is don't touch him, he doesn't like it when petted one bit, he won't be mean but will run screaming like a girl so... he's the best though
now i have a new group of ee's, one so far has turned up a rooster they are about 7 to 8 weeks right now, and just this morning he jumped up and cuddled in my lap, yet he is still a baby so we'll see when those hormones kick in.
I don't think good roosters are that rare my guess is its 50/50 chance 1 out of 2 roos type of thing
