I'm still new at keeping chickens, but have had a few different breeds. My Barred Rock chickens are wonderful - calm & docile, friendly, eat out of my hand. Not too fussy when I steal their eggs from under them. They growl and coo, but rarely peck me. I've had the same experience with two groups, 25 each, at different times. My RIRs are about the same, a bit more curious and approachable than the BPRs, but some will bite a chunk out of my hand if I try to take eggs from under her. The RIR roos are fierce (except one I've had, the calmest, friendliest roo I've ever had of any breed). Also 2 groups at different times, 25 each. One group of Australorps are even more docile and don't mind being handled at all. I've never been pecked by one. Only ever had one Aussie roo, but he's a very good boy. Never chases or threatens me, but won't let me touch him, either. Guards his girls like a dog against other roos or danger, leads them to the best treats, and herds them inside at night. All of these birds were hand-raised in the brooder. I've got one EE hen which was a rescue, don't know her history, but she keeps her distance from me. Meanest chicken I've ever had - and he is a dangerous, sneaky, vicious little sh*t - is that Old English Game bantam rooster. We only tolerate his bad attitude because he gets along with the other birds and is the best chicken alarm system we've ever had.
