Are you getting chicks, or Adults? What aspects of them are you curious about?
Well aside from what I mentioned in my first post, they tend to be prone to broodiness (some will never go broody though) and are excellent mothers. Even though they are small, docile birds, they can hold their own around other breeds, even full sized birds.
The roosters tend to be docile too, Out of the dozens of roosters I've raised I've only had 2 show aggression toward humans.
They do better in confinement then other bantam breeds. Make sure their coop and run stays dry so that their feathered feet don't get caked with mud, and be careful if you get a lot of snow, even though the are pretty cold hardy, they have a lot of trouble walking though snow, even just a couple inches.
That's all I can think of at the moment.

Enjoy your new birds!
