The type of hive isn't an issue with chalkbrood.  If the hive is healthy to begin with and doesn't have other issues (like a heavy mite load) then it will be able to survive and recover from chalkbrood without any help.  The bees will dispose of the dead brood, clean up, and the hive will go on.

Chalkbrood is a fungus.  The last I checked there aren't any fungus's that are very skilled with a compass.  :-D

It is related to several functions....humidity, hive health, and genetics.  Prolonged high humidity (rain) can trigger an outbreak, stronger, more hygienic hives can eliminate it quickly.  Occasionally there will be poor genetics/hygiene and a queen will need to be replaced, but under most circumstances the hive can clear it out on their own.
