> How and why in the world does a queen lay drones only?
A late mated queen or a queen who runs out of sperm in her spermatheca will lay only drones. This is because drones all come from unfertilized eggs and are haploid (have only one set of genes), while workers and queens come from fertilized eggs and are diploid (have a pair for each gene in the set).
