Brahmas are delightful aren´t they? They´re my favourite out of the various "breeds" I have here. My ISA hens are tame, I can pick them up, but they can be a bit spiteful to other birds. My Dels are very smart, but bolshy and very stubborn and not so easy to get hold of, although I raised them from tiny. My Brahmas are so sweet-natured, easy to handle even though they free-range, by far my favourites. Are your new ones youngsters? I always find they go through this teenage phase when they get independent from the hen, and they get quite silly and scaredy-cat, say "run from the monster.." (me)I'm not an expert rooster analyst, but I think the aggressive behavior would make the situation worse. I agree with the other statement about holding the rooster down instead. It's the same with rams. We would never hit our ram or rub his head--they see it as a challenge and you want to fight them. Sort of like "bring it on." I've only had one mean rooster and we didn't keep him. I'm very patient, but if I've tried everything, then he's got to be culled. He was a blue andalusian and super mean. My oldest brahma roo is a sweetie. My two new ones seem so frightened of me, but are still mellow, as a brahma is. I love the brahma roosters. I'd never get a blue andalusian again though. He would flog me any time I was around.
