I don't think you will go wrong with any of those breeds. I would get the Australorps in a heart beat, if it was my choice. Really, though, it's whichever breed you like the most. I think Australorps have beautiful heads, as well as being great egg layers and having good temperaments. My husband's least favorite color in chickens is black, so they'd have to be the only chickens available anywhere, for him to choose them. I would ask if you can spend a few minutes watching the birds before you choose. Egg laying and personality are important. It's also a pleasure every time you're out there, to enjoy the look of your chickens, too. Plus, you might be able to notice if some of the chickens are picking on others or seem more flighty and skittish while you watch them. Asking the seller their opinion is also an excellent idea. Different strains of a breed can vary on how they look, lay or what kind of temperament they have. It all depends on what traits the breeder selected for or didn't bother to select for. I think you'll do well, no matter which ones you choose. Congratulations on getting chickens! I love having chickens around. I think they're a wonderful addition to our home life and the eggs taste amazing.
