Well, my Cochin has gone broody at least once each summer. My French Black Copper Marans have gone broody more often and have raised chicks quite well. Many French Black Coppers go broody, but not all, so ask before buying eggs or chicks. Kraienkoppes (easiest to buy from Ideal) go broody, hatch, raise chicks for 6-12 weeks, then start all over again starting in February and going all summer long.
Maybe you've already seen it, but if you do a search of the internet for the words [broody ussery] you should find an article about broody hens. That should set you up.
