Hello there and welcome to BYC!
You have certainly come to the right place for all the fun and learning!!
YES...you MUST keep Australorps!!! LOL I can tell you, they are the only breed I will keep anymore. My Black Australorps are the most docile, gentle, very affectionate lap sitting chickens you could possibly own. They follow me around like drooling puppies and beg for me to sit with them. I can't sit down without them wanting on my lap! LOL They are very cold and heat tolerate, they don't have many of the laying issues that other breeds have since they mature later in life than other breeds. (gives their laying machines time to fully develop before laying) and they are just all around sweet birds. I will NEVER keep a flock without some Aussies in it!! And when they molt into their new fall feathers each year...they are gorgeous! Aussies have more feathers than most breeds...they are just so soft and fluffy! So yes, consider the Black Australorp!!! The Blue Splash Australorps are very pretty if you want color and are just as sweet as the black.
Good luck on your journeys and if you have any questions about things, feel free to ask. Oh and stop by our Learning Center too for all kinds of great articles on all the aspects of keeping poultry... http://www.backyardchickens.com/atype/1/Learning_Center
