I have had murderous buff orps, and I have one last Black Australorp who is """""" on wheels. She fought off a hawk last year and took 30 plus stitches to fix the gashes down her neck and the chick wasn't even hers. Friendly however, she is not. Lays like a champ.
So far the more of the Rocks have been friendlier. Though my black rock roo is headed for freezer camp at this rate. Part of attitude is genetic, and my buffs obviously came from stinker birds and the Trio of BA's was soo bad, I sold off two. But of the over 100 rocks, I've had, I've had one mean one and he's not that bad. Far better odds, over all, from several sources.
If both parents of the eggs in question are friendly hand reared birds, usually you get good offspring. If not, then luck of the draw. Lots of people buy birds from a guy with hundreds of chickens and turkeys that I know well. But when he wants FRIENDLY stock, he comes to get my birds. I do spend a ton of time with them and have always culled harshly for attitude, it shows in their behavior. People who live very closely with their stock tend to insist on only friendly breeding birds. He doesn't and his birds are not fun to catch or handle and he knows it.
He even just comes here to pet my turkeys.
So you get what you pay for in birds from a breeder sorting for attitude as well as type.
