My wyandottes are very good with me, but my two older SL hens - 5 years - make sure any new ones know their place. While not excessively harsh, they don't let an opportunity for a peck to pass them by. They remind me of Catholic school nuns - even down to the colors of the habits! They make sure everyone remembers their place. They are not aggressive at all with me, and have eaten out of my hands since they were tiny. My 6 month old boy, going to KC, is great with me whenever I pick him up, - which is often - but not so nice to my bantams. Leaves the big girls alone, though. I put it down to being a teenager with raging hormones. I have his sister, and she is fairly timid, although I have noticed her adopting the "peck" habit of the other girls. So, no aggressive ones here. They certainly are beautiful to have in the run - I love 'em!
