Hiya, Phillip, and welcome to BYC! We're glad you're here!
This article by one of our members covers a lot about several breeds of chickens and their attributes or lack thereof. It might help to look through a few of them if you're still stumped.
You might need to get a few when you get your girls, haha.
What color Sussex did you keep? I'm a fan of the Speckled variety and I'm pretty sure most of us would tell you how much they enjoy their Australorps. It's always on a chicken, by chicken basis, though, so you never know since they are animals and unpredictable after all.
Keep us posted--we'd love to know how things are going! Thanks for joining and welcome to BackYard Chickens!
