All of my hens are sweet and easy to handle. However, a couple are a bit mean to their flock mates. Interestingly, some of the best cuddlers with me are the bossiest in the flock. It’s almost like sitting on my lap is related to rank. For a high ranked bird that is not mean to those beneath her, I’d say Barred Rock. For pure sweetness, my Speckled Sussex, Blue Laced Red Wyandotte and Buff Orp. Best cuddlers, though they are sometimes aggressive in the flock are Brown Leghorn, Black Australorp and Light Brahma. So it’s really all over the place in my flock.
