My first flock that I started out with were also the Australorps, but I found the roosters couldn't be trusted for me to be able to turn my back. They went to freezer camp. I had other breeds after that, but now I only have the Bielefelder's and I'm sticking with them. My rooster is a good boy.
I have 20 shipped ones to add new outside blood to my flock of them, and 3 from my flock. I was trying to pick the bigger and darker brown ones. I prefer hatching the egg's, rather then buying chicks.
