Do you have a reference for this?  Here in Australia, it is common for 
beekeepers to take combs from the brood chamber and replace them with 
foundation in the belief that it will reduce swarming.  They do not use 
drawn combs as they believe that the need to draw the foundation out is a 
mechanism to reduce the swarming impulse.
