Pros: Extremely friendly and broody, gentle
Cons: No defensive instincts, terrible in wet climates, not alert to dangers
I like silkies but it is a myth that they are "The Most Broody Hens" They are consistently broody but pathetic when it comes to raising chicks in anything but a secured environment.
If you want the most low-maintenance broody bantam, go with a cochin or better yet, an American Game Hen. This way the chicks will grow up with a clue on how to forage and survive from threats.
They are perfect for little kids and folks that have a place to put a defenseless puffball
