I was planning on getting black australorps, mainly because of their size and their dual-purpose. I don't eat meat personally, but if I wind up with a partner who does I would feel better about knowing where my family's food came from than buying meat chock full or hormones and raised cruelly. I've read they are good cold-weather birds.
They are an adaptable breed. I had some of the hatchery Australorps when I first started out. The 2 roosters were mean. Then I got the breeders Australorps that are bigger than the ones from the hatchery, and decided that I like them better, so I sold my hatchery flock.
