Out of the three breeds of chickens I got (1 black australorp, 2 ameracaunas, 1 buff orpington)
I was not expecting to recieve a (fairly) aggressive, not veyr social black australorp. if anything, I was expecting her to be the MOST docile. If I am filling th efeeder/waterer, and my hand looks like it is posing a threat to her, she will go after it and bite me, causing me numerous blood blisters. I started tapping her on the head when she did it, and that has helped sigificantly but she trusts me a bit less, but it's better than having a chicken that poses a threat to everybody around her. She is also my dominant chicken. My friendliest chicken is probably my ameracauna, then my B orpingont, both are very docile and have a lot of personality.
