I'm going to give you two links, the first an article about broodies, which lists on the first page the breeds that are pretty well guaranteed to go broody. One of the is Kraienkoppes, I had 3, and all were great broodies.
The other is Henderson's, which tells for each breed how likely they are to go broody.
I have two American Game hens.They go broody at the drop of a Hat.
But I aslo have these broodies:
two old english game bantam hens
two silkie hens
one buff orpington hen
one light brahma hen
one partridge rock hen
two muscovy hens
one pearl guinea hen
